You plan it. . . bazinga! 
How about a HRA / 2aHawaii / Place to Try Out Handguns Day (rifles too, 7.62x39 max caliber), at Koko Head Shooting Complex, Action Bay One?
Possibly June or July,
possibly third Sunday of the month (don't have a confirmed date in July yet),12:30 to 4:00 as long as there are enough members around to help take down the tent and clean up. To participate, HRA membership is required, twenty bucks a year, five bucks for the event. Many here are already members. There are "HRA Fun Shoot" events at Action Bay One almost once a month, pending pandemic, open to all HRA members. Seven to twenty yard targets, paper and steel (pistol calibers only), watermelons if you bring em. Ammo

not included. There will be RSOs and Koko Head safety rules apply, however, no five round mag limit or slooooooow fire rule, but be safe. So up for discussion, anyone interested?
