Here's an aerial view of one of the past corn mazes at the Petaluma Pumpkin Patch. Each year, the owner creates a new maze--and it's never an easy one. Typically it takes folks 45 minutes to find their way out, but if you buy a postcard of an aerial view of the maze, you might be able to get out a little quicker. Or not. On weekends, the maze stays open in the dark, late into the night, and is especially popular with teenagers.
