The saying is you can never have too much info -trail data for hiking the Continental Divide Trail.
At some point, however, a person has to make decisions. Currently, there are three viable options for the southern terminus. The Crazy Cook monument is now considered the official, and choosing this route is about 60 miles longer to Silver City than the Columbus Route, a route many have taken in the past for various reasons. Keith, trail angel in Deming, and Carole and Hugo, trail angels in Grants have been very kind and supportive.
I have one month to hike, and have decided to begin in Palomas, Mexico, eat lunch (you need a passport to do this) and book it north where I'll get my car in Grants.
I haven't heard much about Antelope Wells on the Mexican Border. Perhaps that one will go by the wayside.
Even if the route is eventually marked and official, I think the logistics of this remote trail will always make to alternate routes on the CDT a given. The common saying is no one can hike this trail the same way.
