It seems like the troop goes on a lot of difficult outings that make me nervous

Yep. Troop activities are exciting and challenging.  Just wait until your son joins the Venturing program!  

 

Challenging activities help boys to grow, and keep them interested and enthused. While exciting and challenging, the activities are also designed to be age and ability appropriate for boys in this group, and are as safe as we can make them. That's why we insist on things like gear checks, prep trips, and following troop procedure.
