My wife Kat and I and some of our Phish friends were "bus guides" on a memorable trip from Shea Stadium and other cities to Lemonwheel in Limestone, Maine. It was an unforgettable and fun trip. That year, Phish partnered with a bus tour company offering rides to the festival from many cities in the Northeast. It's never happened again (probably due to no bus tour company taking on the mission), but it would be a great idea.

Maybe you should suggest it to the Rocks Off people, especially if you know other NYC people who'd be interested? Feel free to start a forum thread and organize this on the forum!
