Well, it took me a week but I am back on the bike commuting to/from work. The traffic around here is crazy and it takes me less time during traffic to bike home/to work than it does to drive (and that is taking the back roads!).
My commute is around 15 miles and has some good hills - I forgot how much harder the hills are with two paniers - and the waterproof one with a laptop inside! It is a great workout.
