Thanks for the birthday wishes and the ride suggestions. :)
I ended up riding the Rock Creek trail from Lake Needwood to just short of the DC line. With the 5+ miles from home to the trail head I did 40+ miles. The sun was in and out of light clouds. I was never quite warm enough to lose the long sleeve jersey but I frequently had it zipped down and the sleeves pushed up. I lost the trail at one point coming back and ended out at the road at the wrong place and needed to look at my iPhone map to figure out what to do.
My bike got a well deserved cleaning when we were done.
