Image from Barnes and Noble.I finished reading $20 Per Gallon by Christopher Steiner this week. It's an eye-opening book, to say the least! Now, I'm not saying that I've bought into this guy's whole program but he's got some valid ideas of how things may look in the future. It boils down to less SUVs, more electric cars, less jets, more electric trains, fewer far-flung suburbs and more active downtowns. Oh, and the end of Wal-Mart as we know it. Doesn't sound half bad to me!
