OGCA is not affilated with C&E gunshows.

The OGCA application for a table for this show clearly states that alcoholic beverages are prohibited.
The application must be signed by the applicant.
So, in my opinion, the OGCA had they right to do as they did.
I was not there for the incident, so can not comment on what happened or what was said.
I know that early Saturday morning it was certainly a point of discussion.
