I attended last yr's open house, took a couple of days off and drove from WV, my car is stored in Madison, WI, and want to restore it and I have been looking around for shops. I had a great time, spoke with many of the guys from the shop, got price quotes, etc. Northern WI is beautiful in May and while you are there, take an hour out of your day and take a free tour of the Leinenkugel Brewery, not the best beer out there but the free samples afterwards are pretty tasty none the less.
