One possible option for a membership fee...
Charge $2 per league set as TBA fee. For this the bowler gets one free game voucher, transferable for use by any TBA member.
Most people won't miss $2. Keener bowlers who bowl more than one league pay more but get the benefit of more practice games. And anyone who simply doesn't want to bowl practice games ever can sell their vouchers if they want, especially in centres with expensive practice rates.
If the average bowler bowls 50 sets per year, thats $100, x 20,000 members = $2million/year. 50% to tba, 15% each to local and state associations, 15% to advertising/TV., 5% to Nationals
As for revitalising Nationals - no disrespect to John Coxon, but it needs the services of a professional management team. Nationals are too big for one person and volunteers to reasonably handle.
To the tournament itself - get a travel company to put together a National Bowling Holiday package together, where participants bowl their events, but also do the major tourist events/sights in the venue area. Then sell it to the bowlers as their chance for a great holiday as well as a bowling trip.
Add in some relevant seminars/coaching opportunities/pro-am events, and TBA can start value-adding. Would it matter if the tournament ran for an extra week if it was full and TBA could pick up an extra $100K from clinics and courses?
Make the bowlers there feel special - they might want to come back then. Announce every group onto the lanes. Add titbits like - welcome to Doris from SA, this is Doris 25th Nationals, woot woot etc.
Have a cash prize, presented then and there, for the best series each squad - most over average. Presented on the apprach with a bit of fanfare, every bowler in that bowlers centre will hear about it. It's about raising the profile.
Rachuig - I'd love to see a pre-Rachuig Baker format tournament, with all 7 bowlers having to bowl each game. Pick your best 3 for the clutch shots at the end. A 9-game round robin would be great spectator fare, and over in 2 1/2 hours, or 3 hr with a top-4 knockout for TV. $70 bucks each prizemoney gets the winning team $5k - bit of incentive. And bring back the sledge just for this event
