The only thing you need to enter the Hospitality Tent at the Convo is an active Bobcat Club membership. You are also permitted/encouraged to bring non BC members in with you. They have 2 or 3 tvs going and a good selection of food and drinks is available for purchase at a reasonable price.
Are they still in a cash-only mode for this venue? I wasn't in it for the home opener, but last year, that's what we encountered.
