Sounds like a perfect job for the troop Historian! If you have a scout that wants to take on that role, he could go through what you have, research on line, talk to former scouts, etc. As a relatively newer troop, he could make a pretty complete history. I like the idea of documenting trips with photos and recollections of the outing by the scouts. I find scouts take much more interesting photos than adults do. We tend to pose people or have everyone looking at the camera, where scouts tend to take more random pictures that better tell the story.
