Raced a thunderstorm home on my commute. Same one that has Boston under a tornado warning. I got outside and my first thought was "...that's a lot closer than I thought given the radar."
I made it home about a minute before the skies opened. Normally my commute is my "happy outside exercise time." I'm on a hybrid bike with a pannier and don't really try for speed. Normally I average ~10mph on the commute. Today I averaged 14mph to get in ahead of the storm. Close call!
