If you're into Yoga at all there is a class that I'd like to recommend on the not so far south side. The teachers name is Ricky Heldt and he is the owner of Open Lotus Yoga. I've been taking his class for a couple of years and its a great class for anyone at any level in your yoga practice.
All you need do is bring a mat (he also has mats available if you don't have one), a donation of any amount (suggested is$5- $10) as a portion of the proceeds from every class goes to the Wisconsin Humane Societies Milwaukee campus and bring a great attitude. There is parking in the lot available as well.
I just figure this would be a great way for those in the group who practice yoga to meet other yogis in a comfortable and non judgmental environment.
