So, this weekend I was supposed to finish my certification to scuba dive with open water dives Sat and Sun. Saturday went well. I'm not learning as fast as I would like and still get nervous in places, but I had a good time and left the lake feeling energized and wonderful!
Sat night I woke up with a bad pain behind my knees -- esp the left one! I had to make a decision early in the morning, before I really knew what had happened, and I had to decide NOT to dive today.
I think what happened is that I am not kicking right and actually seem to have inflamed my tendons!

At least I know what happened.
So, right now I don't know when I'll finish the certification, but I WILL finish -- even if it is AFTER my trip to Croatia!
