Climbing in Mexico?

Hola amigos,
I'll be spending the next ten months in Toluca, Estado de Mexico, a city west of Mexico City for the next ten months. I was wondering if anyone has beta on climbing in that region or climbing in Mexico in general. Any info you've got, from gyms to crag etiquette I want!
Gracias!!
P.S. Yes Portrero Chico is already a goal :)

Don't know what kind of routes interest you, but we found plenty of multipitch moderates on our trips: there.

Thanks!! This helps. I won't have a rack so unless I find a friend with one I'll predominantly be looking for sport climbing and for me for leading nothing above 10s. And anyone who has beta on gyms in Toluca as well is much appreciated.
