One of a small series of caches along Newport Pagnell Road, Wootton.
OK so it's not really an obelisk but it's close enough.
Why though does it have a sign on it stating "Private Road No Public Right Of Way"?
Should we be there?
Not much in the way of parking close by but you should be able to find somewhere safe.
Best done on foot or cycle in conjunction with the other caches along this route.
