Meandering among museums and monuments with fellow global citizens in America's front yard. Hobnobbing and nose-rubbing with politicos, wannabe politicos and wannabe wannabe politicos. Creeping yourself out on The Exorcist steps — and beware a tipsy tumble. Chowing down on DC's infamous half smokes and chili dogs with Obama. Cocktail-swillin' and hip-shakin' the night away — question is, hip-hop, salsa or lingala? Blazing the urban frontiers of up-and-coming 'hoods such as Columbia Heights and Northeast.
