Dan,
As I'm sure you know, the highway through Mt. Vernon connects with another one that heads north about two or three blocks into town. I believe, the car is a few hundred feet up that highway on the right. There is a little nicely maintained house and the car is on the Mt. Vernon side so you'd see it first. There is a driveway and a bit of yard in between the car and house, and the two are the same color, kind of a light tan I recall. If I can go to the December meeting and you would be kind enough to give me a lift I could show it to you. If not though, it should be pretty easy to find, just look for a camp car and it'll catch your eye.
Thanks Again, Taylor
