Let me know when your route takes you through Center City Philadelphia
Seriously, I wonder how many people there are in the Philadelphia metropolitan area who would buy E85 and/or race fuel on a regular basis? Maybe we should open a race gas station here? With VAC and Helix Motorsports right here in Philly, NJMP in South Jersey, Englishtown Raceway in Central Jersey, Pocono Raceway, Dover Downs in Delaware, and all the local clubs (BMW, Mini, Porsche, Subi, Audi, Mustang, etc) you'd think there'd be a sustainable market for high-octane fuel around here?!?
Keep a lookout for a poll asking this question on this and other car enthusiast's forums. I'd consider going into this business if the numbers work out.
