Ash -
I was there about 10 years ago; the "collection" auctions, buys and
sells constantly. Probably a few Duesenbergs are still there:

It's been longer since I've been to Harrah's collection (now the
National Automobile Museum) in Reno, (actually, when Harrah was still
alive), but that was a "Schlumpf-like" experience - a few nice cars,
but also great quantities of ordinary cars. The Nethercutt's two
museums just 20 miles north of Los Angeles is quite good and now
serious about authenticity and well-endowed for the future. Last
summer, we went to the Blackhawk Museum, east of San Francisco. Like
the Nethercutt, it has a beautiful building and is a nice presentation.
I had a great visit to an amazing, private collection of Indy cars a
few months ago, near Corona, California.
