Before heading to Mexico for the first leg of D.C. United's CONCACAF Champions League quarterfinal against Queretaro F.C., I was given the same gentle warning from friends and co-workers alike, to tread lightly and be careful in and around town. And you tend to forget this cautionary counsel, for a couple of different reasons:
First, Queretaro is difficult to get to from a travel perspective, at least if you don't live in either Dallas or Houston. The city and municipalities of Queretaro average 1,900 meters, or 6,200 feet above sea level, so it's somewhat isolated by nature.
