Hello,
Ok, I know I am a bit late with the pictures. Been quite busy with work as of late and had to upgrade my flickr account to hold the amount of picts to upload.
On the weekend of June 7-8, I participated with the Windy City BMWCCA chapter at an autocross held at Tire Rack. This the sixteen year. It is a blast. They have a pretty neat tests track that gets setup up. It is not very fast due to its being short, but it has been setup for a lot of fun.
Here are a few pictures from the event.

A couple of the managers have M5s.

A new M3 was ready to go.

There was even an Alpina Z8 participating. He was really smoking the tires too.
Here is a link to the rest of the pictures from both days.
Both days were great except on Sunday, you'll see that we had a bit of a weather issue. Midwest was in the midst of getting really pounded this spring. Tornado sirens went off and everything, but we actually finished the last session and got packed up before the rain hit.

Storm clouds are bad, umkay.
