My daughter, granddaughter, dh and I went up the road to Lake Michigan to a place her instructor took the college class about fossils. We walked the shoreline and searched and carted stones for 2 1/2 hours, and then realized we still had to do the return walk. We did find many that she was able to identify from being thousands of years old. It was actually just late afternoon but the way dh took the photos it looks like evening coming. We were all very tired but happy, and that entire time, never saw another soul.
