I was able to obtain the loan of the book: Arizona Trails South Region by Peter Massey and and his friends from Adler Publishing.
All of the descriptions are complete now for thirty-three trails in the South Region which is along the Mexico border and around Tuscon. That makes over a hundred trails in Arizona all mapped out with downloadable tracks, and descriptions of directions to trailheads, mileage, map availability and major things to see on the ride.
The world is a book, and those who do not travel read only one page.”
For those interested in a "winter" ride - this could be the place. There are mines, mountains, lakes, trees and deserts. From short day trips to one long 2 day adventure.
