From what I understand (please correct me if I'm wrong), Steve Plunkett (the fellow who owns this amazing property and car collection) was fortunate to have a father who pioneered the birth control pill. He has since passed on and Steve gets residuals from each sale of that little pill. The car show supports a local charity.
yeah its some medical thing from what im told also. My company made all the doors and trim for that place just before i started to work there and they said its an amazing house and hes a great guy, very down to earth.
