Report AGS or Lagos de Marino to Laredo? in Ajijic/Chapala/Guadalajara Posted April 30, 2017 I know the buses to Laredo take the Aguascalientes/Zacatecas route because it is shorter and cuts driving time. Now that the bypass around SLP is completed, is it as fast to use that route to overnight in Saltillo? Heading to San Antonio and Saltillo is halfway between Lakeside and San Antonio. Will also be towing a 5x8 enclosed trailer.
