Lock a Campground

We were camping at Harpeth River Bridge Campground and got out on Friday Sept 18, 2015 driving around to see the local sites We came upon the dam sign on 49 W and decided to take a look at it. Beautiful and then we saw across the river and got on 12 and found the right bank recreation area really nice. We saw the campground and wanted to look around for future camping trips but was stopped by your host and told we could not look around on the weekend to come back during the week or on Sun after3pm . Was the rudest person and really discouraged us from wanting to camp in the campground. All we wanted to do was drive through and see want kind of sites and facilities was available. Was very disappointed that we were unable to do so
