If the crowds at the Milwaukee location end up being similar to the Cleveland location you should think about going there with your son right at opening time on a Sunday morning. The first few hours are much more family-orientated and low key ..... but all the riders there were supportive and super friendly no matter what time we were there on that weekend.
Not sure if I'll be able to make the Women's Clinic or not but I'll have to keep it in mind. If you haven't seen their website yet you should check out the WORS Women's group. They will probably have a group doing the women's clinics.
