BTW, I forgot to mention that many houses and hotels have cisterns, in the form of black cylindrical tanks, on the roof rather than in the ground, or in some cases they have cisterns both places.
In any event this is a fascinating place to visit. If ever there was a place that celebrated art and beauty it is Oaxaca. One very prominent Oaxacan once told me, they say we *zapotecs* are not very pretty people, but we have art running through our veins. And the latter part of that sentence is definitely true. If you like art, beauty, color, creativity and originality it is hard to beat this beautiful and in many ways unique city.
