Via Alex Ross, an article in Slate about Charles Ives's house, up for sale if you've got a couple million. Actually several million, and some field artillery, as you will want to shell a few recently-built architectural obscenities that affect the view. (Seriously, look at that thing they built in the field across the road. I ask you.) Prospective buyers should be aware that the neighborhood has severely declined since Ives's day, with the influx of tasteless arriviste investment bankers in the late 1980's and throughout the 1990's. Don't get me started. But drop me a line if you want help with the shelling.
Measured, post-knee jerk addendum: On the other hand, Edward Steichen's house is less than a mile away, and last I knew that hadn't been turned into a museum either, but neither had it been torn down in favor of a generic House Beautiful monstrosity. So maybe there's hope.
