Finally overcame my fear of door knocking today, and tried to get my first permission to a pre 1800 house. (house was 1782) Well I got rejected for "personal reasons". They guy was very nice and also told me people have asked before. I wonder if there is a cache or something very very personal hidden there? If that's the case I wouldn't want someone digging on my property either. Oh well, there's plenty of fish in the sea and at least I am beginning to realize the worst anyone can say is "no"
