I saw you were at Quoddy Head, and I've been there too its amazing (I think it's the most eastern point in the USA).
Union Bay is the name of a campground ( suppose the nearest city would be Ontonagon, MI). It's also funny to me that the best gnocchi I ever ate was in the U.P. Another cool spot in the U.P. is the ski jump at Copper Head- you can climb to the top and see just how high those ski jumpers take off from, it is amazing.
So many beautiful things to see in the USA, but not enough time or money I suppose to see it all (mega millions would cure that lol). I really want to see the Columbia River Gorge in Oregon/Washington someday, along with Big Bend National Park.
