I have done a lot of it during the winter when it was a snowmobile trail. There are quite a few yet for me to do. The best way to do it is with two vehicles. You know that routine.
Some sections can be easily done by walking out and back and then moving on to the next crossing. It is about double the walking doing it that way.
Some have done it on bicycles and except for a bruise or two from a fall or two did OK.
I do not know if it can be done with an ATV, but that would be an excellent choice of transportation.
I plan of getting up there sometime to complete what I started over the winter. I just don't know when that would be.
I'd really rather not cache, but I am helpless in the grip of my compulsion!
