You know, if any of you are in/around Southeast Michigan, the Shelby Club here hosts a few track events every summer that we attend. I think we're doing the June 3 "Driver's School" event at Waterford Hills in Clarkson/Waterford, MI, as well as the July 29 event (Hot Laps at GingerMan) in South Haven, MI.
There are usually a lot of Mustangs (obviously!), but there are many other makes/models that attend, probably 45% to 55% non-Mustangs. It's a neat crowd. P.S. In case any of you think I'm crazy enough to go out and thrash my new S60, no worries, mate. We/he will NOT be running our daily drivers at these events!

We usually do the Labor Day Classic and the Harvest Happening, too. BTW, for what it's worth, GingerMan seems to be the track of choice. They tend to hire flaggers so that you get more track-time (rather than having to actually work a flag shift). We're trying to keep our eyes open for any club doing things at Mid-Ohio -- that's another track we'd like to see one of these days, but haven't yet had the chance. (Well, we were there for the World Superbike Series a few years back, but only as spectators.)
Thought I'd let you know, because I think it would be neat to see some Swedish action at any/all of these events (but I'm not crazy enough to do it in *MY* new car)!
