I missed ironMung this week because I couldn't make it Tuesday. I went in last night and even though I hadn't lost much I still got owned by the collar choke from the guard way too many times.
I'm headed there for the 12PM BJJ class tomorrow. Call (416) 256-9952 if you have questions, or I can try to answer them here. The place is far from "crowded" but with about ten people on the mat last night I smacked into another group a few times.
