... I'm wondering if anyone has decided whether one has to obey them in Indiana?
I've been through the Indiana criminal code several times and I can only find schools and government buildings as being off limits with no provision for private establishments to post signs.
The one sign I've ever seen in Indiana says "NO FIREARMS (except for those carried by law enforcement and legally licensed private citizens)." Because of the wording I'm thinking it's unenforceable in Indiana.
I've searched the archives here and I've not come up with much to go on, thus this post.
