Would it be useful to try to establish just what constitutes a switchback?
Definitely. There is some debate here.
I think one requirement is that the up-slope and down-slope side of the trail must switch from one side to the other.
I am not sure whether the number of degrees in the turn (how tight) should also be included.
I've got it.... any turns in question should photographed and displayed.
And does a "switchback" mean the actual turning point, or is it the straight section of trail
between the two turns???
