There was a post somewhere about a guy getting stripers through the ice on the Hudson River near Albany ...... He didnt post any pics and at the very least there is a good chance he was BS'ing.
But ....... the river does freeze... there are definitely holdover stripers and it could be true.......... but extremely dangerouse.... could you imagine falling through... the current would have you away from your hole in a flash.
I have one buddy who fishes some bays and coves .... ties a rope around himself and to a tree on shore.
Personally ... i think i'll just wait till open water before i risk my life for a fish
