From Little Rock north and west to the borders I know about 50...
You're new here so I'll take it easy but asking for locations is like farting at a cocktail party. We typically don't share locations publicly and almost never with newcomers until we know who you are. This is not only for our security but more importantly for the preservation of the locations.
My advice is to start posting some of the locations you've visited (no need to give specific details on where it is and don't use the locations real name) and include some history and/or a good story. Over time you will become trusted enough to start exploring with full members then things will open up a lot more.
It's seems harsh, maybe a bit cliquish but over the last decade, after seeing places trashed or burned down and members arrested for disclosing information publicly, it's what things have evolved to.
Take a look at the Rookie Forum and read some of what's there, it'll help you get acclimated to the social norms of this community a lot faster. Start here:
