I've never seen tailgating

Most games are colder than football weekends, too.
That being said, I have been known to have a beer or two at Rohr's before/after a game. When they had the 20 year reunion of Beth Morgan Cunningham's team, the group was partying at Rohr's (staying at Morris Inn) so that was the closest thing I've seen to a large group getting together for Wbball.

I would suggest to make a "Winter Sports Weekend" out of it (they actually just discontinued this - but you can do your own). Sometimes there is a weekend with Hockey/Mbball/Wbball all at home - not always all 3 but usually 2 out of 3. Stay at Morris Inn
