Not biting but they are there like popcorn?...yes, been there and seen it..
Here is a perfect example of what you guys are talking about.
As it gets dark, most of the time the crappies will shut down for a good hour until it is completely dark before the night bites would kick in.
Try this sometime... (from my Lowrance HDS), set Fish ID on with High Chirp Sonar, and turn on Night Mode...(lots of dinks and some nice bigger fish on this brushpile)
Here is the world of dinks!
