Today was the day of truth.  An appointment with the orthopedist to find out if my cast had to stay on for another 2 weeks. 
The result:  no more cast.  I was down-graded to a splint that, though I am supposed to only take it off for seated activity, it can also come off for.....running! So so long to a sweaty, gross, and perpetually damp thing constraining my wrist.

The best part of the whole appointment was that through 5 weeks with a cast on, during which time my wrist had locked up and my forearm muscles severely atrophied, my watch tan was still very much intact, as pictured below.  Frankly, I'm not sure whether to be proud, or concerned.
