Seven. Mostly sunny, still cold but over freezing point, Westerly winds @ 7-8 mph, gusts in the 20's. Started at Gail Borden Library in Elgin, mostly stuck to the Fox River Trail. I only saw a few other riders and not many hikers out. With yesterday's mini ice storm and the resulting black ice in places, had to be careful. I finally hit a patch of almost invisible ice on a curve under the bridge at Longmeadow Parkway and I went down hard on my right side. Painful but still able to ride, just going slower. If memory serves, this feels like a broken or bruised rib. As of this writing (Saturday, 2 days later), feels much better so I'm pretty sure its just a bruise. I'll see how I feel later but might take an extra day off to be sure.
