Guys like that give riders a bad rep. More like cowards because most Porsche drivers are level headed which you showed. You won't have to look far, they more than likely hang out at that some store or one like it close by. Its about "see and be seen" I see it all the time here. They don't really ride. They hang out at stores and gas stations etc. Any place where they can be noticed.

Ghostrider has excellent advice. Just show up in another car about the same day and time. Take all the pictures you can.

I'd probably show up in an old beater with no insurance and "accidentally" back over a couple of them. But then again, I'd be to worried that "I" would be the one that got into trouble.
