Has anyone ever heard of a "tour bus"? A coworker showed me one she participated in but I can't find anything about them (or how to get one going). I am thinking of trying out something like this for my girl scout troop (maybe a Girl Scout Garden "Daisy" Chain with flower stamps or something like that?).

Does anyone know anything about these?

Troop 907

There was this one in NH: http://www.atlasquest.com/boxes/clue/index.html?gBoxId=42340

and this one in TX. http://www.atlasquest.com/boxes/clue/index.html?gBoxId=6147

If you do a search with "tour bus" as the name of the letterbox, it looks like there were a few others too!
