Just started my commute this week, 16-20 miles one way. The longer oath is all these little windy trails through montgomery country north of DC-though pretty and relaxing, I think with all this rain and mud they will soon be the death of me. I didn't want to turn my beloved and only back into a communting behemoth, so I opted for a chrome courier bag, which has the added benefits of making me feel really cool. I still have more commuting gear to buy, but the ride is the best part of my job.
