We got there right at 5 till 2 on a Sunday -no parking so we parked and walked elsewhere - there is sign saying tour starts here-you can not go in without a guided tour- but Nowhere did it say where to go to get the tour -we walked down and started coming up and an old guy asked if we knew how to read? We said yes and he said that doesn’t mean you can wonder around(we were not) we knocked on a door w cobwebs that led to believe they weren’t open anymore. Another couple was there to. Due to him being so rude we all left. I won’t donate money to rude people or send them business. I should have asked him if could find people skills before opening a business. If he doesn’t want people to go beyond the sign put a rope up or a gate. Or maybe a simple “wait here” sign for those that can read.
