I had to go out of town for a couple days but didn't want to miss my commute -- so I rode to work on Monday, left my bike in the office overnight, and rode home yesterday. Still got in two commutes, although my mileage was like one. I'm back on my touring bike for now after a fun couple of months commuting on my Merckx Corsa. It's getting dark enough in the mornings where I want my best lights, which are mounted on my tourer. I'm debating swapping them over to the Merckx, so I can keep riding it until the weather gets cold and I have to start carrying more gear.
