Actually, you'd be surprised how much historical preservation goes on in Buffalo. They have a few large neighbourhoods of well-preserved older housing (including the Darwin Martin House, currently undergoing major restoration, and three other Wright houses in private hands), a Frederick Law Olmsted park system, and their downtown is considered to have a number of fine examples of skyscraper architecture, including buildings by Sullivan. They have their issues, too, but they're nowhere near the level of a Detroit in that regard. Seriously, you wouldn't think Buffalo as a great place to see architecture, but it actually is.
