The emergence around me seems much less coordinated than 2007 (granted I don't live where I did then, though I'm not too far away). I think this was because we never got a deep soaking rain until yesterday. They've been emerging in pockets across the area as little rain storms popped across but after yesterday's soaking a whole bunch more have come out (some are still molting!)
@brad indeed I saw it, and it's part of why I went for a walk just now! I can hear them clearly at home now so figured I'd go out and grab some pictures
