I am always struck by how slavishly people on wilderness trips will adhere to a schedule, even when nature conspires to mess their plans up. This often leads to unwise decisions "because we just had to get back for the first day of classes," etc. This is just not so if you are looking a suicidal stream crossing, or something similar. You adjust by breaking out your food reserves (or by following Presumed Lost strategy) and enjoying a somewhat longer trip. A lot of folks have gotten into trouble by insisting on pressing on, regardless of conditions.

Spend a fair amount of time on first aid, and most particularly, encourage the kind of thinking that will allow the Scouts to improvise things like splints from the items they are carrying with them.

Congratulations to you for doing this. I t is much less spectacular to prevent incidents than to respond to them, but prevention is a much better strategy.
