Does anyone else set up on snow cover, if there is any and drill holes near edge towards clear ice. Do you think fish use snow cover as hiding place to scout for food,does snow cover prevent spooking fish on sunny days. Has anyone ever set up equipment or hang out on a large tarp or something else be sides a shack to prevent shadow in water below ice. I've noticed if I come up on hole to soon fish may drop bait and quit biting, or is this just my luck.
