We had a rather large meet there one day several years ago. Took up just about the entire place.
I remember when I hosted an open carry at Knotty Pine in Broken Arrow we packed it in too. We actually spilled out of the meeting room and in to the main dinning room. Sadly as time has passed both groups as well as open carry enthusiast have declined since then.
It would be nice if there was still a large interest in it but sadly most people have realized they have the right and moved on to other things. Even out in public an open carry spot is still very rare though there does appear to be a slight growing. I still can only count on one hand how many times i have seen O.C. outside of get togethers.
