some good pics. Wish exif was intact, interested to see which lens you used. In some of them you must have been at the widest angle, as there is a ton of barrel distortion and some pretty bad vignetting. That's not your fault neccesarily, but I heard that there's plugins for photoshop with specific lens profiles that correct that. That's why I downloaded cs3 and am looking for plug in packs to try it out.
I lived there for a while, calle 74 x51 y 53. Right near santiago. such a badass citySweet dude, I've spent tons of time in Merida, usually spent at Hotel del Gobernador, just down the street from that pemex. Walked by it daily.
Where did you stay in Merida?
Where are some of the other photos from? Some of them from chiapas?
