¡Bienvenido al mundo desarrolando!  In a word, it's chaos.  The sights: an open air market with people crammed together selling fresh fruits, vegetables (many of which I don't recognize), a woman with 15 crates of eggs to sell, a group of men selling tools; busses driving through the market, getting within inches of goods being sold; a young girl carrying a bowl on her head--perfectly balanced; young boys getting on and off busses selling bags of water to passengers; a man wearing a hat that says "Old Fart's Wife"; houses, pieced together with corrugated metal, guarded outside by roosters and skinny, stray dogs; women, gathered in a stream washing clothes; people running across the highway to catch their morning transportation; old men sitting on steps in the plaza, talking about the day, passing the time; open-backed trucks entirely filled with standing people; signs--an equal mix of advertising American companies, political ads, and graffiti; an open soccer field, high in the hills.  The smells: the fire used to make tortillas on the street; the smell of trash, rotting; of pollution, much of which is contributed by 30-year-old busses; but mostly, the smell of wet, the jungle, the afternoon torrential rains, the plants everywhere--in Colorado they are small houseplants, in El Salvador, they're trees; the air: thick, warm, wet.   A vacation to the third world is not a relaxing one--there's what you have to do before you go: getting shots and taking pills (if you're a cautious soul), planning routes and then changing them, and there's the explaining to people why you're going on vacation to the developing world and you're not staying at a resort...and you're riding local busses, the ones that are 30 years old.  There's the warnings--the crime, the robberies, maybe even rape and murder.  And there's being there--watching your bags against the crime you've heard so much about, watching waht you eat so you don't get sick, finding your way around, handling the chaos.  Although not relaxing, a trip to the third world can, if you let it, open your eyes, show you how other people live, and give you an authentic experience.  And you may even find some tranquilidad along the way.
