Think pink.I don't know about you, but the White House is a little bland for my taste. And it certainly wouldn't fly in Argentina, a very culturally rich, colorful city. It's no wonder, then, that presidential meetings take place at the pink house, la Casa Rosada. Come on a weekend and you'll get free reign to wander the hallways and gardens. Be sure to admire the ceiling as you walk in, and if you come at night, take note of the lighting. Here's a hint, Miss Piggy would certainly approve.
