Mexico: Guadalajara to Zacatecas
I'm in Guadalajara and want to go to Zacatecas. As far as I can see in the Guia Roji, there are at least three major possiblities:
a) Road 23 via Jerez de Garcia Salinas
b) Road 54 via Jalpa
c) Toll Road 80D and 45 via Aguas Calientes
I'd be very grateful for any hints and recommendations wrt which road to take with regards to landscape, traffic, pavement quality...
Many thanks in advance
