My family used to spend our Summers in Ely, Minnesota, fishing on the Canadian side of the border.
We stopped going there when they outlawed the use of motor boats in Canadian waters (in that region).
We last went to Crow Duck Lake near Kenora (Winnepeg), the fishing was outstanding, most of the anglers "catch-and-release" so the lakes stay plentiful.
This year...Bimidji, Minnesota in the Spring.
