Ron, all your pictures are fine and each one worthy of comment.
The shots of Biltmore -- which is less than two hours from here -- make me want to go there again, this time with my Sony S75. My wife and I visited The Breakers in Newport last fall and I took a few shots there. Unfortunately, they don't allow interior shots, and no doubt that's the case at Biltmore.
I don't have any old cars, but like many other people, I always enjoy seeing them, such as the old Pontiac. Is it yours?
What is the brick building that has the acute angle? It looks like a ship's prow.
