If you post it, they will come.[/James Earl Jones voice]
If you are not sure how a particular place might respond to OC, go there yourself and see how they respond to you OCing there. Or pick a place generally known to be "safe" - like Starbucks. You do have Starbucks in West Virginia, don't you?
Just do not go somewhere and ask the management if they would be OK with a bunch of OCers showing up. Doing that will give them the opportunity to think about it beorehand, as opposed to seeing how polite most OCers are.
If you post a time and place and nobody showed up but you, go back to your post and provide info on how nothing bad happened to you and any positive interactions you had with staff, management and/or other patrons. And then post a time/place for the next "event". If you post it often enough, they will come just to see who the heck you are. Like the carnival barker, it's all about getting them into the tent - the show itself is not that important.
