Fuel prices haven't affected me any. I'm one of the lucky ones in that I live in the middle of nowhere surrounded by hay meadows. So anytime I want to fly all I have to do is walk out my front door with the plane of choice. Glow fuel prices have gone up for all of us, but the LHS where I get mine hasn't had near the mark up some people are talking about, I think it's gone up 2 - 3 dollars a gallon, and I can live with that since the price was very reasonable to begin with (i.e. considerably less than some where saying they were paying prior to the increases).
