Anyone know of any laws preventing teens from being on the trail alone? I have 2 teens out there now, ages 14 and 17 (he'll be 18 in 5 weeks) and apparently a sheriff and park ranger are looking for them. They passed the word with other hikers and said something about "unaccompanied minors". Our kids have calling cards with their blog info and parental contact that they are handing out. We've had other section and day hikers contact us, send us photos and updates. But apparently someone checked out their blog and saw their ages and contacted authorities. Any suggestions?
