The INT is essentially a marketing tool for the various sponsors. As a former State Coordinator, I can attest that I never made any money - I broke even once. The INT is well produced and has a different "feel" with the announcing, background music, and banners - so it is more expensive than an AWSA local tournament. It was designed to be more novice-friendly and require far fewer officials. It is not as Type-A competitive satisifying as an ELR tournament. But, because of the marketing structure, it is much more controlled and it requires a more controlled State Coordinator. So, you don't have a bunch of distributed LOCs putting on the tournaments. It is just a different model.
That said, it would be nice to have the AWSA more user-friendly for the new skier or the new site. If you are growing an area from scratch, it takes longer to get your Senior Judge in slalom than it does an MBA - and not too much less time and effort. With kids in school, a full time career that involves a lot of travel, and the demands of homeownership it is no suprise that fewer people are involved. You need several people, an expensive boat, expensive personal equipment, lots of time, extreme levels of patience, and confluence of various people's schedules, and a very supportive and flexible family to make it all work. It just doesn't happen like it did in the '70s and '80s anymore.
If we restructure to reduce the demands and keep the fun, we can stop the contraction and perhaps grow again. Evolve or go extinct. It is not the strongest that survive, but the most adaptable.
