If you had to be in a wheel chair this is it

The Tank Chair

Tank Chair is a Custom off-road wheelchair that can go anywhere outdoors. Conquers Streams, Mud, Snow, Sand, and Gravel, allowing you to get back to nature, and can also climb up and down stairs.

Ran across this item from the 2008 CES when searching for pics from the 2009 CES. Wonder if Medicare would cover that?
