Where to?
Hang with a dude at a taco stand all day interview him, eat tacos with him, ask him about his life, his aspirations, interview taco stand patrons, wipe the sweat from your brow and ponder global inequality, ask him for another brain taco, go to the toliet and crap water, have a Sol and a cigarette. Anthony Bourdain meets 30 days meets existential long shots of life from a Gus Van Sant movie (would kill the hand-held mic and blast something slightly obscure and lite-etherial-sound-rockylike maybe
Mogwai?I'd also go to a movie theater and get popcorn and put all the condiments on it (hot sauce, jalapenos, nacho cheez etc.) and order like 7 beers and weird everyone out. You'll probably see something like No Country for Old Men which should just be hitting theaters there.
Where are you going again? Is this a bromance fueled trip? Are you solo, like a young Hemmingway? Will you have an annoying girlfriend in tow? My tips are these: Don't do anything at the hotel. If you must ply the p-ssy with Miami Vices (just ask for one at any touristy place) and ditch to check out street life, do it! Always buy newspapers from street kids, always go to the nastiest looking cantinas and always go to the most expensive looking clubs for laughs. They will have names like "Cubo" or "Apolo" or "Bar 7 Club." You will have the most decadent night of your life for like $50-60. Never pay for flowers.
Always go to a public beach that is in the middle of nowhere.
Don't forget to wear sunscreen.
