For those of you who have never had the privilege of stopping by Hugh's house... let me say this... He and Minta are some fine folks who are as hospitable as the day is long.
Two weekends ago I had the disctinct pleasure of visiting with them overnight... and seeing Hugh's collection in person was also a privilege... Those BBQ guns in particular-- I will post a couple of photos soon about my visit.
The only snag I had on my way was
FINDING the place 
. It was after dark when I arrived, and the road is not well marked at all. Finding it in the daylight wouldn't be much easier! Their house is far enough from the road that the agent may even give up!
Hugh- my suggestion is to make the appointment to see you after the sun has gone down and let them try and find your driveway! You may never even hear from them again!
Let us know how things go!
