I'm getting back into bike commuting full swing after missing most of July and late June due to a knee injury and vacation trips. I rode 4 days last week, which was quite an accomplishment because we had severe thunderstorms almost every afternoon -- and I somehow managed to avoid them. I didn't avoid getting my first flats since I started biking to work in April 2007, and managed to get two in one day. The second flat left me stranded, so I had to walk my bike home over 3 miles in cycling shoes. Not fun and I've taken precautions so that hopefully won't happen again by adding a frame pump to my bike.
