At 8 years old and armed with only an ax, identical twins Geoff and Mike Howe constructed a one-room log cabin. It's little surprise, then, the brothers have moved on to greater heights in the design business. In this case it's their one-of-a-kind specialized vehicles built at Howe and Howe Technologies, where CEO Geoff and chief engineer Mike lead the crew, and their wives, sisters Tracy and Tammy, run the office and perform marketing duties. Among the Howes' inventions are the Ripsaw, a high-speed military tank; the Badger, a personal assault vehicle used in law enforcement; and an all-terrain vehicle called the Subterranean Rover.
