My Sandbox is Bigger than Your Sandbox And for $200, Ed Mumm will let you play with the heavy equipment.

The Magic Kingdom. The Bellagio. The vacant lot outside of town where you can dig giant holes.

Ah, yes, Ed Mumm has big dreams for his company, Dig This. He foresees nothing less than America's next tourism hot spot, with bulldozers and steam shovels competing head-to-head with novelty attractions, amusement parks and Celine Dion as vacation musts.

Crazy? Mumm doesn't think so. In 2004, while building a home in Steamboat Springs, Colo., he rented a bulldozer and other heavy equipment to clear his land. "It was an extensive earth-moving operation and I had a friend who coached me," he says. "After a couple days I was having such a great time, I started to imagine how many people don't have the opportunity to use these machines."
