We tried a LOT of things back in the day(mid/late 90s') to play winterball (I live an hour north of Duluth), and it just never worked out well. We get too much snow, it is too cold, and the equipment is too fussy to work out well. After struggling for a couple of years, we found out it is just easier to wait for the temps to warm up and the snow to melt. Good news though....should get 70 this weekend!!!
