I'm probably joining both this year - I did a few events at race city this year and the Porsche club one was great - seemed like some real enthusiasts showeed up - noteably some of the other members of this board. Not sure if I'd do the non-track events where people spend more on their wheel tire packages than my car is worth
I'll probably join the Calgary sports car club as well - they seem to have a real mix of people, with lots of great events.
