That mud puddle Flathead Lake is the largest freshwater lake west of the missippi, BTW... (about 188 square miles)
A guy can flat out dissapear in there if you're so inclined. I spent some of my youth there, helping with stock, and fly fishing. My Great Grandfather was a good friend of Howard Copenhavers.
Truthfully, there's better places to hunt around here, and with better access.
Just sayin' Thats all...
