where to buy Guia Roji Tourist Road Atlas or map book of Mexican roads lakeside

Sometimes they have them at Superlake, SAT.
If they get to Guad., Sandi's book store on Tepeyac always has them.
Only 2 places that I know of.

I found one in obscure book store on the North side of the street on the North side of the Chapala plaza about a year ago.

While ours have always come from Superlake, it seems they move them around.  We gave found them in the same display and the newspapers and magazines in the past.  But the last one we purchased was to be found on a display just off the end of the register counters.

A fallback source is any Sanborns throughout Mexico and some OXXO's, especially those near or on the cuotas.
