It wasn't backpacking, just a day of skiing with my son (then 20) in a National forest. A few hours from the car we met a family group, 4 adults and several kids. The adults were passing around a bottle.
We said hi and kept on going. A few hours latrer we met 2 girls, about 10 yo, crying and scared. They didn't know where their parents were or where they had parked. We gave them water and candy then said if we couldn't find their parents we could take them to the Ranger station.
The girls' parents were at the same lot where we parked. The adults were drunk and angry! Accused us of trying to kidnap the girls.
My son is much bigger than I am and at that time had a very quick temper.
My son got angry fast. he said "Which do you want, the forest Rangers or the State Police - both are just a short distance away."

They all got in their cars and left in a hurry. This was abuse.
We did tell teh Ranger but forgot to get license munbers.
