This Saturday and Sunday, June 8 and 9, it's Michigan's "Three Free" Weekend, where you can fish, ride off-road trails, and visit state parks, all free of charge.
An invasive alga known as didymo, or "rock snot," was discovered in Michigan's Au Sable River, raising concerns with environmentalists and the local fishing community.
Everyone likes when things are free! It's Free -- times three -- this weekend in Michigan! Here is a chance to go off-roading, fishing, or visit a state park.
