I'm with Joe and the $5.00/gal. It is currently hovering at $5.19 in my area.
With that price, I won't be going to larger events I normally would. Last year, when diesel was only $3.00, I dropped an easy $600 plus on fuel to Colorado and back. This year, it's just not feasible. Mind you, if I had a stupid supply of money, I'd still do it.
Does the purse affect me? Not really, if I go, I'm not going expecting any cash out of it, although it's nice I'm there for the fun of it.
Nice of you to ask, though! Way to go, guys!
