This week has been an interesting experience. Last Tuesday, it appeared that Tropical Storm Joaquin was going to meander about and then head this way late Sunday or early Monday. So, I decided it would be prudent to go ahead and fill up my truck. While I was there, there was a line up of cars refueling and about half of them had gas cans they were filling. Wednesday comes along and the little piddly tropical storm had become a hurricane. My son goes to fill up his car and he has to wait longer than I did. The guy at BJs says he's been outside all day filling propane tanks. Thursday comes along and the barely-a-hurricane had become a Cat 2 and still some likelihood of coming this way. So, I decide to fill up the empty 5gal gas cans that I'd been putting off doing. We get there and not only is there a line up, but they'd run out of regular and were selling premium at the regular price. Needless to say, I got a bargain with the 20 gallons in cans and went ahead and topped off my truck. Get to the grocery store to buy the usual Disaster French Toast supplies, which appear to be required by law here since the store was almost out of bread, milk, and eggs. Of course, by Friday, it had become apparent that Joaquin, even as a Cat 4, wasn't going to hit here. (Although, we've had rain for a solid week, high winds, and tidal flooding. That's different from a hurricane, how?
)
I guess my point is that people are starting to react much quicker to oncoming disasters than they have in the past. If you think that still having a couple of days before the event happens will mean you beat the crowds, you need to think again. More people are "getting" it and that means that by the time the balloon actually goes up, it will be far too late for you to do anything about it. The last time an event was coming thru, people were almost waiting until the day of landfall to stock up.
Have what you need before you need it or you may not be able to get it.
