Yes Kev, many times. It was a hoot to sit in the presidents chair and sleep and dine in the same rooms that many famous people did. At the time your father-in-law and I would go there with Ed Isaacs and I was the only guy shooting one of those "outdated technology" guns. (as per J.A. Grady). Would love to do it all over again now that I can afford it more.
I've got one of those pins somewhere, have to dig it up.
