Yeah, I just got one from doing half the drive with them. They're staying over night in carbondale, but the route goes straight through Glenwood Springs. Sorry I forgot to mention something to them, I was having WAY too much fun in the NSX! I'm sure they'll peek on the forum tonight. Someone did mention it also, but who knows..... good luck!
BTW, Colorado cars have a BAD tendency to get rock chipped to death. I think I DOUBLED mine in the short 400 mile jaunt at mach 1.
