I prefer not to have the headaches of another large group to corral. I plan meetings and conventions for 25k+ person conventions and so don't want to get another one. However, anyone can join us but I am not actively looking to get others outside the KAMO area.
I actually think ACA in combo with WS would have a better job of getting something done. They have a much broader source of cyclotourist enthusiasts that they can easily reach. The problem is everyone wants to make money. For instance, our 4-Day KAMO tour is strictly volunteer organized and conducted. It costs nothing to join us except you are asked to chip in on the research & marking the route costs if you can (about $200 total or $10 if 20 people go on the tour). Of course, when it is free, you have to pay for your own lodging, food, etc. but the purpose of KAMO is to just bring cyclotourists together, not to make money or make this the "best" or even the overall cheapest tour. I truly hope this becomes organic in that the members start to tour together where ever, other regions form their own "KAMO" and then maybe years down the road, all the "KAMO" groups can get together for a Rendezvous.
I remember by Boy Scout days and freezing my ass off at the Trapper's Rendezvous in Kansas. It is quite large now.
