Campouts

You need :1 troop campout to achieve Tenderfoot.
                Two troop campouts to achieve 2nd Class.
                Three troop campouts to achieve 1st Class.

You need 20 days/nights of camping with your troop to get Camping merit badge.
Camping merit badge is required for Eagle.
Keep track of all the campouts, and keep it in your scout binder. (Where you went and dates of campouts)

I suggest you go on EVERY troop compout that you can. Once you turn 14, you get too busy to do scouts until you are 17 1/2, and then you panic frantically to get it all done.
