This Is Drivel

This is seven kinds of cool:

Dennis Parker, looking for a place to play with his trains, cut a trap door in the floor of the kitchen in his house and laid out the track for his pike in the crawl space under his house. Thirty-six years later, the layout sprawls across the footprint of his house, but he still has to get about on his hands and knees to see it all!

Fun is where you make it.
