While I have been Crossfitting on my own for a year or so, I just recently joined an affiliate last week.  I joined CrossFit USD, one of San Diego's newest crossfit gyms, and I'd say one of the better outfitted.  The facilities are the USD sports teams' facilities, and have ample room, and loads of all the necessary equipment.  Check them out at www.crossfitusd.com.  My first two workouts went really well, and double under ability proved to be very valuable in our 3 sets for time of 3 backsquats and 70 double unders.  I'm excited to get trained myself, and the man running it, JP, has been great and I'm excited to see what kind of workouts/programming he comes up with. I'm sure with his Seal, rugby and crossfit experience/background I'm in for some real fun.
