I fished there many moons ago, Yeah you need a snowmobile unless it freezes early before snow. The problem with that place in the winter is the snow is super deep and it get super slushy. If a guy could sled in there before Christmas you would do ok, also its a hot spot for drag racing so it would be rather loud. Brundage won't let you park there but just before that is goose creek parking lot, groomed trail from there. Also they drop the water level a lot.
