I can't exactly join you, as I'll be driving my own boat to Tracy Arm that day (!) but can you tell us a little more about the tour? Who are you going with? I know quite a few folks who would love to fill up a tour, but who won't get on a 6-pack boat unless it's 5-Star safety certified.
What time are you going? for how long? what all is included (ie: lunch, etc.?)
Better not for now... signatures get me banned!
