I am going to presume you have not recently been to Philmont. (I just returned 705-U03/Trek 16) In defense of the boys, a returning timeline can run something like this.
1.You get off the trail at 1700 ish, stinky as the only shower opportunity on the trail during the prior 11 days was a cold one and as you know you cannot use scented soap or any deodorant give the bear procedures.
2. You immediately have to start check issued gear back in, getting non trail gear out of security, getting assigned homebound tents etc.
3. You are then marched over to the mess hall to get dinner with the other homebound crews before it closes.
4. You then get your tent settled a bit only to have to make the closing campfire
5. You are then exausted and go to bed without showering.
6. You then get up, eat breakfast with the homebound breakfast crews and then get shuttled onto a school bus to make transportation connections such that getting a shower just doesnt happen. This reality is exsacerbated when AMTRAK personnel refuse to handle or load Scout backpacks and other gear such that the boys literally work up a sweat loading the train.
or
one recognizes that teenage boy hygine is often a developmental area and though a Scout is clean, a teenager can smell rather quickly even after a shower.
YMMV Greatly,
