On Saturday I took the kids out for a bike ride on Saturday while Stephanie did her weekend ritual of deep-cleaning the week's detritus.We rode a combination of Columns Drive bike path and Cochran Shoals hard pack trails for about 11 miles over the course of an hour or so.  We stopped in the middle for a bit of nature observation on the Chattahoochee River.  Maya and Devin enjoyed talking to the ducks, but they just quacked back.  We also watched plenty of kayaks and river rafts going by, and the occasional canoe.
