This article is about a young man who is helping coach Lobos de Quito, described as Ecuador's first American football team. It appears they practice in Parque Carolina (I recognize the plane in one picture).

I've seen a few people post here looking for American football players, though they may be looking for pick-up games. This might be of interest, anyway.
