Young couple goes on van tour of US, boy comes back with van - no girl

Given his skill set as an outdoorman, it would probably make more sense for him to disappear into a forest. If he can stay there for 6-12 months, most folks will forget what he looks like.

Authorities will probably be keeping an eye out on the homeless camps in parks for him where eventually he'll pop up is my guess.
