An interesting phenomenon in the backpacking community is fear mongering on the trail. Even more so, our ability to buy into it so quickly.
Several years ago, we hiked the Buffalo River Trail. The first section of trail had more elevation change than we expected or were conditioned for. As we worked our way up one particularly steep section (for Arkansas), we met a man coming down the hill.
He said, “Just wait until you hit the first hill on the next section!”
