It’s s Northern Wisconsin Thang. While we DO have a cabin ‘Up North’ I don’t think the guys do this at Bear Camp.

Wikipedia actually said hundreds or even thousands which I thought was a bit over the top. Unless it was done as a perpetual stew back in the day. Sounds kinda the same anyway.

Booyah. Probably a lumber camp thing along with buckwheat pancakes.
