And there is Coal, though that will run out eventually.
Outside of the City we've got mad sprawl problems though, the old river towns like Sewickley, Coraopolis and Oakmont, aren't so bad because they usually have a rail line close by and are relatively compact but Wexford, Cranberry, Fox Chapel, Ross, Shaler and the like are going to look not so good if gas goes up to $7-$10 per gallon or higher.
The South Hills are rather spread out but they do have the T rail in their favor.
We'll just have to wait and see what oil does over the next 3-5 years or so, perhaps even the next decade before the future really comes into picture.
