Read a little of the article about the Kek. Sounds tough! But then, it's easy to find a challenge like that anywhere. All you have to do is GO OFF TRAIL. They could pave the Kek, and it would still be just as tough if you walked parallel to it, 100' away. I don't like the idea of knocking down bridges, or leaving blowdown on the trail, just so folks can imagine that they're following in the footsteps of our exporer forebears. You want stuff to trip over? Bushwhack. I do, much of the time, and I enjoy it. But when I want to use a trail, I like to see the trail kept up (and I do my share), not full of stuff someone else wants to trip over.
