Me and my cousin dumped sleds in Mille Lacs a couple years ago.
Edit: after checking the map to make sure I spelt the lake properly I noticed Brainard isn't on the lake, and realized she hasn't lived in Brainard since my cousin graduated in 2002, she lives in Garrison now, since her nice house is on the lake...
Her husband's family is insanely rich and when he died she got a good chunk of money and built a nice house on the lake. It sits most of the time, I think next year I'm gonna go up there for the summer and spend a month or 2.
