All week the weather here in Chicago has been fantastic (of which, unfortunately, the weather report says is going to change at some point in the early morning hours today). In celebration of the Vernal Equinox I am posting some pictures that I took over the past week showing sections of my back yard and of the Lake Michigan & Montrose Harbor area. I hope you enjoy this taste of early spring!
