[Last Dakotan]

Visited Duluth lately ?

Will be there in August. The only thing north of Duluth is pine trees.

Not true.
Drive north on HWY 61. Visit Judge Magney State Park (one of a half dozen great MN parks in the area.) Across the highway is Nanibujou Resort. It's exceptional. Get a reservation early.

Then drive on up to Thunder Bay and visit one of the amethyst mines. Pick up chunks of the red mineral from the crusher for $1/pound Canadian. Then there is a Fort ?? reenactment play in the old part of town...
Lots more to do and see than just Duluth.
