I would say any day now.... I had 2 loners yesterday afternoon, so they have to be close. Typically they last less than 2 weeks, from what I can recall.
Saturday night, they were doing the fly-out by the millions, toward the center of the lake. They weren't landing on anyone or the boat..... but they were doing fly-bys...
Yes, the flies were doing the "fly-by." I ended up going up to the Pond but didn't ride the bike just in case. As it turns out, it wasn't that bad. While fishing, I could hear the buzzing but didn't really have that many land on the boat.
