I really gotta start coming up with titles for these themeless puzzles.
I had eight different southeast corners for this one. The cleanest ones were the dullest, of course, so I went with one of the dirtier ones. I opted for this one in particular once I found a clue for 55-Down that was more "user-friendly" than what I thought I'd have to use. (Something to do with politics in the Great White North.)
