In late morning, we attended a "Oaxaca Orientation" talk at the English Library. The speaker was the local hiking and mountain biking
guy, friendly, but very dry of presentation. We learned that Mexico has a higher bus density than any other place on earth, and that no one understands the Oaxaca bus system. There are something like 10 or 12 private bus companies plying the same basic routes. The good news is that if you can figure out where you want to go and find the right bus, it will only cost you 7 pesos, about 30 cents. Also Larry the speaker said that most Americans living full time in Oaxaca are here not because they are rich, but because they can't afford to live in the U.S. on their meager retirements. We had lunch at a very nice 100% Natural restaurant (according to their own publicity) overlooking the Llano park two blocks from our hotel.
There's a rather colorful bus parked next to the park. The story is that the couple who own it have been driving North from Patagonia since 2008. They're headed for Alaska. I guess they're taking their time.
