I tried this at my club in Central VA. I even had PB members that formerly shot FT. They pooh, pooh'd airrifles. They said 'airrifles would be the last thing they have in the club'. They're an NRA club and I explained that even the NRA has AP and AR events (10M though), and they wanted nothing of it. So, my interest to setup FT there died after that meeting.
As hard as you try, sometimes it can be an uphill battle.

Update: The gun club approved the air gun field target events but they have not approved the wooded location as proposed. This year they will have the field target matches on a police gun range 30 yards wide and 110 yards long. It's a start anyways. They want to get kids interested in the shooting sports and they think this is a good starting point for them.
