Natural History

Nothing like a good, stiff dose of art to clear the cobwebs that a $30 million exercise in folly like "Oscar" spins in your skull, which is why when I got home from "Oscar" and threw "The Natural History of Parking Lots" on the video, it was a nice reward for a trying day."The Natural History of Parking Lots," the 9:30 p.m. show Saturday at the Baltimore Film Festival, probably cost less than "Oscar's" doughnut budget, but it's a textbook example of talent, integrity and passion in filmmaking and how far those can go on how little money.
