Congrats! Isn't it great to get back to something you enjoy? Sorry to hear about your wreck. What did the cab do, cut you off?
I also missed several weeks of riding in December due to getting the flu, vacation from work, and snow (I don't have studded tires and do not feel safe taking the lane the whole ride to work due to snow in the bike lane). I put on 5lbs easily, maybe more, and I'm just now starting to work it back off. I think my body was still craving the same amount of calories I was eating when I spent 5 hours on my bike each week...lethal combination indeed!
