4 days this week, too. Drove on Monday because I couldn't drag myself out of bed, but rode the rest of the week. Rode even when the weatherman said it would be 100% chance of rain two days (wrong!) and rode when there was a 20% chance of rain (and it rained on me).

I just LOVE riding to work. I don't always love getting out of bed 30 min. earlier, and it sometimes takes the place of a "real" bike ride after work- but it's the best mood-booster I've EVER found!!!
