FWIW, not all troops do a lot of hiking. My son's unit camps every month year round, but rarely goes on a hike.

From what you have shared, your son would not be the shrinking violet who would sit there and be quiet while someone molested him. He's so articulate. If the troop follows the 2-deep leader protocol (which they should always be doing) he shouldn't even get into a 1:1 situation that could lead to abuse.
