We got a little rain maybe a week ago? Plus 2 nights that were in the mid 20's this week. And, lots of very windy days.
I keep notes every yr. Firmly believe they come up at the same time every yr no matter what the conditions are. If it's wet, warm, and calm they get big and keep on the ground for a long time (chances of finding high). If it's cold, really hot, dry, and or windy they pop up small and deteriorate quickly (chances of finding low). This hunt was different though, we never find clusters like this!
