May 9, 2009: For my husband's 31st birthday, we got a baby-sitter for the weekend and drove up to Brandywine Valley and spent the morning of his birthday at Winterthur. Winterthur was owned by the famed du Pont family and is not considered one of the world's premier museums containing 17th-19th enturey American antiques. 
The home (well, mansion) is impressive, no doubt. But the gardens..... beautiful! Especially in the Spring! Du Pont loved gardening and spent much of his time and money developing the 979 acres into gorgeous landscape.Verdict: Beautiful and impressive. But wouldn't make it into my top 1000.
