I detoured on one of my "normal" commute routes today to avoid waiting for a long light. E.g. I turned right on the red and rode up just one block and then swung a left. This left me paralleling my normal route. After a couple blocks it also put me in a kind of alley way, that had a nice little stretch of gravel riding.
It isn't particularly noteworthy, but it did add something different and fun for a few blocks of the commute. So, what did you find interesting on your ride to work? If the answer is nothing, try diverting a few blocks just for the heck of it....you might just find some fun!
