Non-expert disclaimer here also.
People are bunched up in palaces for a reason. There’s some quality structure and known production.
But, I avoid those places. I don’t care where you are, if you can find places and populations of fish that are pressured less, you’re more likely to get favorable reactions from the fish, and probably more likely to find quality fish.
I like to try and find bottom comp transitions out away from crowds when possible. This is where side imaging in the summer along with a GPS are invaluable to ice fishing.
