O.K., it's 2:00 AM and sleep appears to be an alien concept again so I''ll just bug you folks.
It is understood that one absolutely must enter the wilderness area via the trailhead on one's permit. But what about exiting? How stringent are the rangers about you leaving via the exit trailhead on your permit?
I ask this because I'm admitting to myself that the hiking schedule planned and already permitted for July may be more aggressive than the old body may be up to. The only altitude acclimation I'm going to get is a single day hike before doing overnighters. If I get a day or so into the overnight schedules and realize I've bitten off more than I can chew, how flexible can I be about shortening my miles and exiting via a different trailhead than what's on the permit?
Not sure if it was this website but somebody wrote that once you're in the wilderness you are actually free to go wherever you want to for as long as you want to on that permit as long as you don't come out to a road. Is that really true?
