Temp 21, DP 16. Ran from home down Custis to W&OD. Was going to head out W&OD, but patches of ice made me turn around. Then went back to MM 3 on Custis, before turning back to 2. Then took Lincoln to 14th and Lynnbrook to Kirkwood to Washington to Wilson, ending at Tranquil Space Arlington. HRM going crazy at times, due to static.
