Translation of macizo

I came on time and two hours later I arrived at Tuxla Gutieres. I was always suspicious here and I never knew whom to trust. Somehow I got to the airport a few hours too early but this is better.
I wanted to explore the city, so I took my Nikon F501, a few rolls of films and headed to the narrow colorful streets of SCDC. Most of the streets were paved and it was easy to walk in this part.
We felt a little awkward to be the only people in the restaurant and felt a little uncomfortable having taken with us another couple. In addition the Uruguayan cook and owner was drunk, but the food was excellent.
