Nah they are in michoacan on a ranch between puradiro and villa Morelos. The Ranch is called La Viga. Maybe on the way back through.
Funny thing about those agave plants, the tequila isn't made from they green blue aloe stem looking part but from the base where the roots come out. It's pretty impressive stuff. Few years back we stopped and toured the city on the way to PV.
Side though.... I onow you arent a fisherman but, When you get to TDF if you don't find a guide and go fish for a monster brown trout I will he disappointed. It's not uncommon to catch a 20 pound trout. Some of the biggest trout in the world are caught there. Think about it.
