Whats the story with E85 / Flex fuel?
 

I saw the ads during the superbowl and took a look at the websites today and it sounds really fucking cool. 105 octane, renewable, clean, supports american farmers, doesn't rely on the middle east. sounds great. sounds really great actually.

so aside from availability and lower mpg whats the catch or should i be headed down to the chevy dealership waving a flag and hugging a tree?
