So I saw a lot of interesting stuff at lca last week, and had a great time of watching geeks in action ;-)
I did attend the morning session with the martial arts geeks. That was pretty cool. Everyone talked about their style for a bit and then did a little demo. Lucky for me, a guy volunteered to be my grappling dummy :-)
After it was done, someone put up a couple of pictures on the lca wiki page. Enjoy. Oh, and no bonus points for identifying the BJJer!
