9/21/2011 6:00 AM 0.10 M M M M There was quite a bit of rain that fell yesterday and through the night. The pre-dawn hours were filled with the sounds of two owls speaking to each other throughout the forest surrounding my home. I could hear them as they moved about going away and then coming closer. Fascinating!

All traffic was slow with hazard lights on. This rain was the heaviest I've ever driven in - including the blinding rains that occur in southeast Michigan!
