<strong>Roost!</strong><br /> Our records show that the modified Jeep classes are the most popular. Races are run over a 100-yard course, and speeds of 85-90 mph are not uncommon. That’s pretty fast on sand! Here are a couple of CJ-5s just after the flag dropped in another photo shot by Eric Rickman for Hot Rod magazine. Check out how the Jeep in the foreground dropped all the excess weight like the tailgate and windshield.
