Thanks. Hadn't heard the name before. Have seen them hot dogging on the freeway, though. A pack of them passed between me and the car I was passing, some of them went around me on the shoulder. I was doing 80 at the time, just after midnight, and I never saw them coming. They were gone in seconds, and the last one (obviously losing the race) almost dumped it on the next curve.
I pulled over and sure enough they started back my way, no doubt delighted they'd find a lone biker. They got close enough to see that I was holding a Sig in my hand and thought better of it.
Pretty typical behavior from the squid set. Terrorizing motorists and others seems to be their bag.
