Oaxaca is a tidy place at 5,000 feet elevation in the mountains, a mid-sized, middle class colonial city. After settling into our comfortable 3-bedroom house adjacent to the Centro Historico, we took care of the business of getting groceries and purchasing airline tickets for our flight to the coast next week. After that, it was all fun and exploration. The Zocalo (central square) is leafy and busy, with benches, shoe-shiners, food vendors, crowds of pedestrians and lots more. Everything is colorful, including the food, clothing, toys and anything for sale.
