Wading shin-deep in the Great Lakes searching for Petoskey stones.
Michigan’s official rocks are discreet, gray things and disguise themselves as nothing impressive. But once they’ve been polished, or even just wetted down by the lake, they show off their lovely, fossilized-coral designs.
The Michigan U-Turn.
Also know as the Michigan Left. Sure it isn’t always convenient. Yes, it may add a couple extra minutes onto your drive. And sometimes trying to zip between cars to pull into the far lane in order to take the “left” (now right) turn is a form of gambling with your life, but nothing is more excited that riding along with an out-of-stater who doesn’t know how to make the turn. I have fond (terrifying) memories of a certain college friend from Illinois who first tried to turn left where she couldn’t. Then missed the U-turn where she should have turned, and tried to turn in the other lane’s U-turn lane.
