DK is considering doing the Tough Mudder event in Austin this year. Some of his co-workers had a team last year and they're starting up one this year.
I think he should do it. He's been working out with me, but it would be something great that he could train for since he cannot keep up with his martial arts training. (He hasn't been able to find a Kenpo school in the Houston area, and isn't ready to start all over in a different martial art.) Not to mention, getting to watch all of the hot guys rolling around in the mud when Wolverine and I go to cheer him/the team on.
