Back in my previous life, me and my buds paid no attention whatsover to gas prices. We went where and when we wanted and if gas was $.99, fine; if it was &1.99, fine. That was not EVEN a consideration. Our main consideration was going "where the sun was and the clouds wasn't", and how much film to bring/buy, and the location of the nearest Target in case we ran out. Hell, I remember more than once us getting together and fretting about not having enough dough to bribe hostlers to break up consists for us!

Wow, those were the days.
When gas prices started going really haywire in my current family life, it had a slight affect on basic travel considerations for family outings, but still as far as fanning goes, I can't say that they have much if any consideration.
