Has in fact re-opened. This past winter was the 2nd season open, 1st season of snowtubing. They also serve breakfast on the weekends and lunch Thurs-Sun.
Great location w/ direct access to snowmobile trails as well and very snowmobiler friendly. Been there quite a few times. Nice place to take a break off the trails.
