The morning was awesome, a few other commuters, and when I stopped to adjust my seat a fellow rider asked if I was alright as he came behind me. Darn nice of him.
Instead of heading home after, I went straight to the bike shop, and then after I trued the wheels and paid for the parts I bought last week, I rode home. In the dark, for the first time, with no lights. I need to buy some. Got home safe, but even on fairly well lit streets it was sometimes hard to see the onramps to the sidewalk. I had simply forgot it was going to be dark when I left.
