Love your site. This information is helpful. Several years ago, I visited my friend in el DF, who was living in Colonia Roma at the time. I was spoiled as she had a driver (!) who took me around to the city–life in the States is all what it’s cracked up to be.
Prior to my trip, I got tons of warnings from expat queer Latinos about visiting el DF. I was on the DL for much of my trip, but I had a great time–the highlight being the six hour “y tu, mama, tambien”-type road trip my friend and I took to Oaxaca City.
