Aww, that was sweet. The storm was not, Ann Arbor got hit hard, we just got a pretty fair amount of rain. The Ann Arbor dot com news site showed photos of people kayaking in Ann Arbor on city streets. High and dry here. Your photo is roughly between Toledo and A2 as our exit numbers are in the low 50's. I was north and east of home today at Island State Rec Area near Brighton and had my first wet ride. I just had showers during my ride, the storm came after I was driving home.
Good luck on your trip, have fun with sister and post some photos when you return!
The heat wave we've had is supposed to dissipate and the humidity will drop making for very fine Michigan bicycling weather!
