Some of the best roads in the Mid-west are in the UP, but not near Manistique :huh: My suggestion is Copper Harbor it's closer and the really good roads are right in that area. Up and back in a day means you'll need to skip riding and exploring the good spots it's close to 8 hours one way. Look close at Hwys 26 and 41 to and from Copper Harbor and Lac LaBelle Rd. through Bete Grise and down to Gay then over to Houghton. The Gay Bar the Bug refers to is named for it's location, Gay MI not it patrons, you guys will be safe there
There's lots more if you guys want to head that way I can give you more to explore and places to eat and drink.Here's a link to the way I go to get there and the 26/41/ Lac La Belle Rd.
