Wow this is great. I visited Oaxaca last November and enjoyed it very much. There is a stamp (philately) museum just east of the botanical garden which i recommend. I'm not into stamps but they are organized thematically and chronologically and so tell interesting stories. Also it is in a nice facility. The botanical garden tour was also worthwhile as the guide explained the background and history of various plants and trees and their locations in Mexico. I like to walk in neighborhoods and so went northwest well beyond the home of Benito Juarez and got what i wanted--to see more normal life. The airport is modern and an easy trip by taxi--nonstop flight from Houston.
