Can't say tha I have seen it other than the commercials. But, going off the "reality t.v." model, My guess is that they aren't the best or the brightest, but, the most "colorful".
Yeah I mean most gun shop facilities are more refined and display there items in well organized order etc.
Where else can you find real rednecks and snaggle tooth smart asses that make the show "entertaining". (reality TV) for the people who aren't in the know.
