I'm listening to Bloombrg radio on XM, and they were interviewing some analyst. He was asked where he thought prices were going in the longer term, 4 or 5 years out.
Answer: $7 a gallon.
Yikes, that's scary.
My E85 experiment makes even more sense, although I hope that when gas is $7 a gallon, E85 isn't $6.50 a gallon!
