Avgas price and the light plane ownership

Anyone worries about what the rising avgas price to the light plane
ownership in the U.S? I have absolutely no doubt that the average
avgas price will surpass $5/gallon in about 5 years. We'll probably
see a significant drop of GA flying, along with a big drop of the value
of used airplanes. It's really depressing just to think about it.

Maybe Lycoming should start researching Ethenol powered aero engines
:-) With global warming, we can turn Canada into a giant corn field.
