Serious question, I hiked the same 12 mile loop in Shenandoah every year for 6 years, and last month I finally walked it the other way | Backpacking Routes - Chatter Central
I used to believe that once you knew a trail, the direction did not matter much. Then I tried it myself on a ridge near my place and saw a whole waterfall I had missed every single time. Now I always plan at least one reverse lap for any trail I know well, because your brain just stops looking after a while.
