wichita ks. the public bus system announced that they will be converting to C.N.G. next year. they will have to build a new filling station. they didnt say that it was to be a duel fuel system. i for got the savings, but it sounded like a lot.
Our bus system here in State College, PA is and has been CNG. However, I just Googled CNG stations in PA. Only 7 are listed in the state and all require a key card. There is a public one here in State College that is at an Exxon station but I would not want to drive out of town!
