South Carolina's main seaport is Charleston. The Charleston Evening Post publishing company owned, for 39 years ending in 2007, the Buenos Aires Herald.
Thanks for Gov. Sanford, we'll be learning lots more about Buenos Aires in the next few days. I've already learned this from the State newspaper.
Trying to drive along the coast could frustrate a weekend visitor to Argentina. In Buenos Aires, the Avenida Costanera is the only coastal road, and it's less than two miles long. Reaching coastal resorts to the south requires a drive of nearly four hours on an inland highway with views of endless cattle ranches. To the north is a river delta of islands reached only by boat.
Better alibis next time, especially in the internet age.
