I took it way easier than usual on the way home, I was able to go to sleep basically as soon as I walked in the door. Good to know an extra 10 minutes or so riding actually results in an extra half hour/hour of sleep. (Also good to know that I can cut through the roadblocks at Civic Center Park during festivals on my bike without getting hassled.)
Unfortunately I slept through the group ride I was supposed to go to and I'm still sleepy.
