[From Craig] According to gasbuddy.com, the least expensive fuel in the country (both regular and diesel) is in Roanoke, VA, which happens to be where we are right now. Today we needed diesel, so we used our GasBuddy app to find the least expensive place in Roanoke. Our 35-foot Alfa, with Jeep in tow, kind of clogged the place up while we were there. It is very busy, because "with-it" people from Boston through Atlanta might show up here to get the cheapest fuel in the country.
If you have a station that beats these prices, please leave a comment as to where it is.
