Latrines in Oaxaca Mexico

We are on our way to Oaxaca Mexico to help build latrines as part of a Medical Teams International group.  We leave this morning and come back next Saturday.  We are thankful that we are not cleaning latrines but building new ones.  This is a big health issue in Oaxaca which is one of the poorest areas in Mexico.  Oaxaca is about 375 miles by car south of Mexico City and has an elevation of 5,000 feet. If we can get to a computer and the Internet we will make posts as the week progresses.  If not we will do one when we come back.
