Hmm. Well, I guess the Gulf coast around South Padre can be designated Official Sane People Beach Area, with a bullet train from Austin. Galveston, while closer, is pretty manky. (Thank you, oil companies.)

There also should be a bullet train to the Big Bend National Park. For the sane people to go camping, hiking, etc. (Which, being sane, they would do in a responsible, non-littering sort of way.)
