Top Gear Crew Attacked in Redneck Territory

I have just watched one of the most frightening moments on Top Gear, a British TV show about cars that was on SBS today. Clarkson, Hammond, and May drive through Alabama with provocative text on their cars, e.g. "Nascar Sucks" and "Man Love Rules OK."

When they stop off at a petrol station, the owner calls over a bunch of redneck thugs on the back of a pickup. What I find hard to believe is how they managed to amass an army of hillbillies so fast. Are these people waiting around for a fight? Rocks were pelted and the Top Gear crew made a run for it. The camera crew was also attacked.

What the Top Gear crew did may have been very provocative and politically incorrect in that part of the country, but I would believe it is protected by the First Amendment.
