I live in New York, and I can't find any here, either. But I spend my work week in Detroit, and they are all over the place there.

In my case, I stay at a hotel (and get ponts, natch ) and there's a Speedway within walking distance. I fill up every week for the trip home. Now it's not the greatest thing since sliced bread, but 8% discount on gas is about 12 cents/gallon at today's prices, and they let me load it up with DC for double miles (on BA) so, for me, it's an ideal FT ploy - do things you'd normally do, just make a slight tweak for the miles.
