I just took over as SM in our troop. While I agree that scouts should be encouraged to explore their options, don't disparage a leader/troop for having camping rules. Remember that a troop uses the Patrol method. If 7 members of a patrol are in tents and one member is in a hammock, he is separated from what the group is doing. This happened on one of our campouts where the patrol leader was in a hammock, and another patrol member got very upset that he was "acting better than the other patrol members."
A lot of times I require boys to pair up in tents. Why? Because Philmont requires boys to pair up and we're preparing for a trek. Please don't assume a Scoutmaster is an "out of touch power monger" just because you might not like a rule... there may be a good reason.
