Recently, I’ve done a number of hikes on very steep trails with lots of loose shale. What that really means is that the surface is very unstable and at any moment your feet can slide out from underneath you.

When I was a teenager, I read a book called Juggling for the Complete Klutz, which seemed just perfect for me. It came with three bean bag balls, and instructions on how to use them.
