I was walking down a back alley from Aldama this morning and heard the distinctive cry of the roof dog. You don't see them often, but when you do they're always the same: a menacing cur roaming the roofs of certain buildings in San Miguel, lunging down and snarling as you walk along the sidewalk. Often guarding no more than a bunch of old hubcabs, some dirty laundry, or piles of trash in a center courtyard, he's the original junk yard dog. He could be harmful if you got on his roof, but where from you stand on the sidewalk he's really just a cultural phenomenon. He's a visible reminder of how our life here is different from our life at home. That's why I love the roof dog. There's so much beauty here, so many misconceptions about Mexico.
