Lancaster Event Center is NOT a posted facility. The posting comes only in relation to the gun show and the specified area they rent. As I understand it (and think it is a pretty gray area), they (the GS folks) have the "right" to post and it is enforceable only in that portion of the complex. There specific rented area with appropriate signage is the only "Victim Hunting Zone" on the grounds. You would have been okay at the Women's Expo (unless it was posted this year). With regards to OC...allowed sure, but did you note the plastic tie in the action (or at least should have been there) and unloaded?
In Columbus, they know Lorimor and simply stay out of his way.....
