Jay,

The only state park I fish is in NY and they do plow the launch road and launch, at least until ice up. I am not sure about Parks launches in PA but I would assume so.

Along with your new winter fishing gear list, you will want to add a big shovel and bags of salt. I and Toothyfishman have been shoveling/salting our launch for years......not much fun but neither is the alternative. I usually lay the salt down thick after I shovel the nite before so any overnite snow is easier to remove the next morning.
