Yes, you can hear the trucks in the background from I-94 but that is the only negative thing about this wonderful place.
Driving across country last summer, my husband and I were always on the lookout for nice, clean, free campgrounds. We found a handful that we remember with fondness and this one tops the list.
Sweet Briar Lake was created by a dam if I remember correctly, and it appears to be a good fishing spot. But if you care about birds, this place is a bonanza. From just our little spot overlooking the lake we watched white pelicans, double-crested cormorants and Canada geese swim around and generally busy themselves, and heard red-winged blackbirds make their lovely background music. Most likely a walk around the lake would have resulted in seeing more species but we were more than thrilled to just stay put and enjoy this peaceful display.
