@Ever Onward, I was wondering about a certain area that you may have been to. I enjoy using my big atlas, and certain features such as look-out towers always seem intriguing. In the Delorme Atlas & Gazetteer for Michigan, (page 27 of current edition), I see one of these at the north end of Underwood Tower Rd. It's roughly east of Wakefield, running north from 28 near Tula, in Ontonagon County/Ottawa National Forest. It's also not far from the Presque Ile River. I was thinking of trying to look for it. Have you been to the tower?
