Commuting from Long Island today because I took the folding bike out yesterday to get the gardens ready for planting. This morning I got on the bike at 5 AM, leaving plenty of time to catch the 5:25 train... and discovered that my rear tire had gone flat. Straight back into the house, where I extracted a tiny piece of wire from the tire, put in a new tube, and eventually caught the 6:37 train. Sheesh, it's cold out there!
