Wow, you packed alot into your trip to DC. I guess since I live so close and have been there many times I do a little bit each time I go. I am glad the vacation was fun despite the tension.
Tubing was alot of fun. I hurt ny knee on a rock but besides that how can you go wrong with a day of just relaxing and drinking. I like hanging with my B and he know what is going on with my R but does not ask unless I bring it up so that works out great.
Have fun at your teaches workshop, sound like so much fun.
