Chad, the last frontier council takes a contingent of like 6 crews to Philmont every year. You guys could jump in on that with just a few boys if your troop doesn't have enough for a full crew. That's how I went and it is cool, interesting to go with guys you haven't met before the training campouts. They do almost a year long planning process.
I used to know the guy that organizes the trip well, but I don't think he is doing it anymore. Either way I'm sure he could point you in the right direction. Call me if you have any questions when the time comes. I could talk Philmont all day.
