We found this fascinating place while driving around one day with the scout troop.
Thinking it was a museum or antique store, we stopped and walked around admiring the antiques spread around.
A few minutes later, Robert, the owner, opened up the building and gave us a tour. It is just a building for him to hold his collections! Just say hi and he will show you his stuff and tell you some amazing stories.
If he is not around, the cache is easy to get to. no need to touch antiques.
