a scratch-built tracked vehicle created by Howe & Howe productions. It's very fast -- its 650-horsepower blown 427 CID V8 rockets it from 0-50 in 3.5 seconds and lets it run up to 80 mph. It's also very agile, sporting a suspension with fourteen inches of travel that lets it handle bumpy terrain with aplomb. In fact, the Howe & Howe guys say it's the fastest tracked vehicle anywhere.
