The Collier Museum is in Florida but I'm not sure exactly where. I had e-mailed them a year or two ago about visiting while I was in Florida but no one replied. I got the impression that it was a private collection. While I was in Florida for the Cavallino Classic this past February I heard a few of the participants mention it. It must be an incredible collection to be private and only open to other collectors.
The Collier family built Naples and still owns hundreds of thousands of acres in the Everglades.
