It's a Pure Michigan rite of passage and something folks have been doing forever. Heading up north, camping, floating down the river, couple of cold ones in the cooler. No harm no foul right?

This summer, that formula could be a bit problematic.

The National Forest Service is now banning drinking on some rivers up north this summer.

According to the service, alcohol will be banned on three rivers in the Huron-Manistee National Forests.

Between May 24 and Sept. 2, alcohol will be banned on portions of the AuSable, Manistee and Pine rivers this summer, and within 200 feet of the rivers. (WXYZ)

And this is serious business folks. We're talking hefty fines and jail time.

You can chance it if you want but if you get caught, fines up to $5000 or SIX MONTHS IN PRISON.

Private lands, developed campgrounds and other designated campsites within the areas will not be affected by this.
