USA climber died on one of those "snow capped mtns" you mention very recently! If you voulunteer in Oaxaca-many of the kids I did Spanish school with there do so @ the orphanage in the city. If you like "real home made ice cream" find the plaza where several families serve it at night! I saw the guvner of state there one night-as pointed out by the guy buying my ice cream from his wifes family! It's real near Domino Pizza downtown area.
If you ride to coast @ Puerto Angel the hotel there near beach (with womans name escapes me now) is good stay-tiny pool good to soak your bones. Restaurant across road(sand floor) from there is OK, not my favorite either.
Good RR! My MX juices are flowing!!!
"If I had my life to live over,I'd dare to make more mistakes next time...I'd relax,I'd limber up.I'd be sillier than this trip, take fewer things seriously, I would take more chances... take more trips...climb more mountains...swim more rivers...eat more ice cream." Jorge Luis Borges, at age 85
