While sitting at the old bayside eating lunch, I asked to see the owner of the now "Patsy's diner" Just outside ( east ) of Constantia. ( Oneida lake)
Here's what I got from her :
YES- there is free acess to the lake for ice fishermen. " Just park over there " she pointed to the east side of the parking lot.
YES- she is all good for fishermen meetings there, like ice shanty get togethers.
Had me two cheeseburgers and home made fries. YUUMY.
