@MattP the sport I always talk about that has the explosive growth model figured out is Crossfit. For a couple of reasons:
1. It's cheap ish. $150 a month, we can't compete there but if you think about it, when I was skiing at @OB1 's lake in Atlanta for $1800 for a 8 month season that isn't that far off.
2. Family aspect. People at Crossfit gyms are like family and it's very inviting. Waterskiing is very hit or miss with this, certain lakes welcome guests with open arms while other are very protective of their site. This needs to change. People don't skip their Crossfit workouts/competitions because it's hanging out with their friends and competitions together. NCWSA has this figured out, AWSA does not.
3. Video production. Everyone needs to go take a look at the Crossfit YouTube page. Tutorials, athlete profiles/stories, competition recaps (we can't even get scores posted most of the time) We have some really awesome and interesting people in this sport, it's time to get them on camera and using them to drive more membership.
