Carry a slingshot in MI, ammo is on the county (road, that is).
I grew up on gravel roads in Michigan, cut my teeth driving on them too. Had no problems at all once you stopped being nervous if you fishtail a little, I would still prefer a rear wheel drive car for it also.
And as a kid yes, walking old gravel roads with a wrist rocket was a right of passage on back roads for kids like me.
