AAHHH
Well, for now, there's the Oaxaca expo right on Benito Juarez and Fremont Blvd. I haven't been there yet - I'm hoping to go this evening to sample some ice creams (last time, I had rose petal!) and buy some authentic artisan wares (I love the headbands) just remember - haggle haggle haggle!
I'll take pictures and post them later!
