We had a half day like that called a "beginner session" at Willowbank with the club. What are the insurances and the like involved? Do I have to organise through a car club or the like? We had a little more cars on the track at a time split into three groups, so about 20 again. I think 30 people would be a nice appropriate number, it makes it considerably cheaper for everyone else.
Would you be interested in helping organise another one of these days? I enjoy BMW Club events but they won't organise another amateur day, preferring proper race days where I have to pay $225 just to run around for fun. I can't afford that!
