Not pictured is Bob's Tiemeyer. If you can't make out the lettering due to the crappy Iphone photo, that's a Primus Mootry, Zinn, Waltworks, Waltworks. Every bike on the track custom and handmade within 30 miles. Sweet!
Edit: I just remembered - a fellow on a Giant showed up at some point, took half a lap, and ate it on the banking (he was ok, just a little shaken up, and he was back out there 10 minutes later). Big-brand bikes = bad karma?
