Not the best day so far...

I bicycle commuted to work every day last week and was planning on doing it again this week, but this morning I broke a spoke on the rear wheel. I'm going to try to fix it myself, but if I have to take it to a bike shop it will probably have to be there a day, which means I'll be driving most of this week. I can go to the gym to make it up those days, but I'm trying to establish the bike as my only mode of transportation.
