I fished again last night, from 4:30 PM until about 9:30 PM. No giants, but some good action before dark. There was a bit of a lull when it got dark, but it picked back up again after a while.
Water temp was 70 when I left. Today was 73 and cloudy, so I'm sure the water stayed warm. But tomorrow is supposed to drop into the 60s and then next week we're looking at high temps in the 50s and 60s every day. So I think it's safe to say that last night's trip was probably it for night fishing for me until next season
