I don't live in the UP, and honestly don't know much about it.
I do however live in the northern lower. Somewhere between Traverse city, Grayling and Charlevoix, depending on the time of year.
I'm sure you can come up with a long list of likes and benefits from living there or here, as many have already done, and not that I want to.....I feel the need to try to talk you out of it.....for your own good. Not that you shouldn't but just so you think about it long and hard before you make any serious commitment.
I'll just ramble my thoughts in no particular order......
Seasons......well....whether it's a textbook season or not there are really only two seasons up here. 1. Predominantly nice, and 2. Predominantly shitty.
Springtime starts off with no rain....this ain't "spring" season, it's FIRE season. Be prepared to watch all your dreams go up in smoke because some city chimp had to roast a marshmallow, or some moron had to burn his leaves....hell maybe it'll be an act of god. Any way it's EVERY year.
Then it's nice for a while decent temps, and some rain maybe. Life is good for a while.
PLANTING season is late, and GROWING season is short. You'll be all smiles when it warms up in April you'll see your trees start flowering in May and maybe get your garden planted right before that June freeze every night for a week that kills everything.
Then the bugs come out, spiders, bees, skeeters, flies, ticks....you get bit....it gets hot and humid, man you can't get away from it. This is AIR CONDITIONER season, while you hide from it all..... but then it turns to TOURIST season and every fucking idiot you tried to move away from is doing donuts with his dirtbike trashing your dirt road.
Summertime heat mellows outmaybe late August or so and it gets genuinely beautiful outside. For about a month. Late september the rains start and before you know it it's October.
Mid October SNOWY season starts and it turns kinda pretty off and on between the rain and the mud, but it's enjoyable. Sometime in November, right around the time a million drunk dudes start wandering the woods with guns, it starts to snow. It snows some more......and some more......and some more and the temperature goes down and down and down, and it's still snowing. Maybe you got out there and enjoyed it a bit....did some sledding, skiing, snowshoeing, made a snowman.....woohoo and it was even a white Christmas. Sometime in January the fun wears off, you get tired of being cooped up hiding from the cold, and you can't walk anywhere without snow shoes or a snow blower in front of you. Winter will break sometime.....it's been warm the last few days, I can't wait.
But, now its February and it's still 30 below, and you realize you didn't push your snowbanks back far enough so the driveway is shrinking. You'd push em back, but that 70 degree day a while back got them to malt a bit and turn to ICE. Your stuck with it. You wouldn't mind it so much, but the ole lady's been driving ya nut's and you don't live close enough to town to get high speed internet. I'd go somewhere and find some entertainment if I could, maybe buy a model airplane, but the road on the 20 mile trek to town is snowy and icy, I bet if I slid off the side of it nobody would find my body for months. Well maybe it ain't worth dieing for.
Thank god for March, it's finally warming up....the snow thaws a bit, the world turns to mud.....then freezes again and snows some more.....fucking snow.....I hate snow....50 degrees today, and I watched the runoff from the drive wash out $250 worth of gravel out of the driveway. supposed to get cold again and SNOW for the next few days.....
April showers bring May flowers.....right......well no....they bring more mud.....your drive is just two ruts now, and the road is a friggin washboard for a mile or so down to the blacktop. but Springtime's here.....sorta....
Buy a digital scanner for fire season.
Keep enough food and fuel to be snowed in for a month or so.
Buy a generator....maybe two
Buy a plow truck.....maybe two
Buy a snowblower.....maybe two
Buy a 4x4.....Two.....
You get it......yeh, one's enough, but you need another to dig and pull the other out. You can even call yourself a "prepper" or a "survivalist" or "self-sufficient"....whatever name you need to put on the box. It's just common friggin sense......It's just the way it is....do it, or take the chance on being dead. Cold kills....
It's a long walk to the auto parts store if you only have one car and nobody to call for a ride.
Keep plenty of gas on hand......it's a shitty feeling when you drive 20 miles back home and realize the gage is on E.....gonna be a long walk.
Move somewhere you know someone.....it sucks when the nearest person you can call for help is 80 miles away.
Sooner or later you're gonna forget the milk.....and have to make the 40 mile roung trip back to town for a $2 spark plug, or a 12 cent bolt......it ain't the time thats the problem......it's the fact you spent 15 bucks on gas for that 12 cent bolt.
Some of them towns up there have some decent stores available......sure. But not everything. Sooner or later you'll have to drive a hundred or more miles for something.
Living up north is great, just not for everyone......All I'm getting at is spend a lot more time considering the bad aspects than the good.
ETA......I ain't trying one bit to shit on your retirement dream. I didn't grow up here I moved here from Metro Detroit, Westland actually. I hunted , fished, and played up here for 28 years before I made the move. It all sounds romantic, happy and fun, when you're a weekender....just be prepared for quite a shock if you try to build a life.
I have a remote hunting place way out in the woods....I wouldn't want to spend all my time there. I have a Fishing cabin on a chain of lakes, and I wouldn't want to spend all my time there. I also have a house in a neighborhood on the outskirts of Traverse City.....I don't want to spend all my time there. Between the three, it ain't bad. Always something to do.....except February-April, thats why I like the house in town.
Best of luck to you.
