Hey Rabbit, sell the mud truck (if you can break even) and get into drag racing. Pretty good bucks all across the country. Our track (Twin Cities) just reopened with new owners after a 2010 shut down. there's been a $2,000.00 race a $5,000.00 race and this weekend another $2,000.00 race in the span of 6 weeks. Most tracks pay $1,000.00 per weekend, but the compitation is tough, and you don't have to be the fastest/big dog at the track too win.
