How much longer will we get to enjoy camping with our son?

We started backpacking without adults at age 13. We did our own trips. I left home at 18 and drove across the country in a 1957 Chevy to go surfing in California.

Kids grow up slower now. You may be able to keep his interest by scheduling some activities like rafting. Let him bring a friend along. Every kid is different but most start to want to be independent sometime as teenagers.
