On the beach in Harbert Mi 49115 - saw 2 at 6:18 pm & started counting. I got to 607 in 30 minutes & stopped counting but continued to watch until 7:10. The flow continued; directional flight, mostly fairly high up. Saw several instances of 2 or 3 individuals doing the circle dance. Light wind from the north; temperature in the mid 70ís. The weather is set to change tomorrow with rain & southerly winds. A neighbor reported counting 33 in a minute from his deck on top of the dune at 6:33. I had to head up at 7:10 so I canít say how long the flight lasted, but this is what I would call PEAK!
