Ok, so has an actual roster been developed yet? I know it's early, but if you start listing names now it gives time to determine how many you "should" have for each lake (how big are the lakes, how much time is available, etc..), and also how much and what support that may be needed. Also a roster now can help settle issues of "certs" and "experience." You can team people based on skill sets and experience if you wish. The idea of surface support (yak, small boat) is a good one, for safety as well as handling trash. A roster now also gives everyone a better handle as far as planning. Makes it easy to guilt people who back out at the last minute.
