I basically told Jenny everything I wanted to do in BA, and she pretty much executed all of it. One of those things included attending a soccer game at El Monumental Stadium. We purchased the tickets online, but had to pick them up at the stadium and provide a photocopy of our ID.
Upon arrival we noticed three things. First, the ratio of men to women with 10 to 1. Second, soccer was clearly for locals only as there were absolutely no tourists. Third, the lineup to get the tickets was at least 45 minutes. Once we got to the front of the line we were told that we both needed photocopies, not just the person that purchased the tickets.
That evening we attended a Tango show which was geared much more towards tourism.
