Same here. Almost all the guys from here have been real nice but the guys I've talked to at shows are always jerks. I was walking through a swap meet one time and asked this guy if he wanted to trade center caps. He looked at me like I was an idiot and told me to quit wasting his time. I was like "Well, this is a SWAP MEET, isn't it?". Apparently sitting on a lawn chair while watching over your rusted junk with no one else around is really time consuming and you can't have the likes of me there trying to trade parts when there are so many sales to be had.
Even my Chevy and Ford buddies always comment about how Mopar guys all act like they're elite know-it-all's. For the most part, they're right.
