They should have certain rides open if it is 40 degrees or warmer, Beast, Delirium, Face/Off, Top Gun, Adventure Express, Viking Fury, IJST, Racer, All of the Coney Mall flats, FoF, TRTR, Action FX Theater, and most of Nick Central and Hanna Barbera Land. I would think it would be a little cold to run Drop Zone because of it's height, along with SoB. Though SoB could be the Scrooge of Winter Fest.
