1- Water. Drink lots of it, soak in a pool whenever you can
2- Get used to sweating when outside.. Deodorant, okay, antiperspirant, bad.
3- Swamp coolers work most of the year..Adding ice to window mounted units produces amazing results..
4- No AC in the ride? Pray for vent windows, and a tint job.(or hope you find one of the old automotive swamp coolers at a yard sale..)
5- Remind yourself, that when you get to hell ( for owning all those "evil black rifles", of course) it'll feel just like home..
And 6- When it becomes unbearable, head to Flagstaff, or Prescott..
