More strange details on Argentina

The latest version of Mark Sanford's excellent adventure is that he was driving along the coastline in Argentina to clear his head after a tough legislative session.

But a few more strange details are emerging. For example, ABC reports that Sanford did not notify anyone in the U.S. Embassy about his trip:
ABC's Joe Goldman reports that a US embassy official in Buenos Aires tells him that the embassy had "absolutely no idea" that Sanford was in Argentina. The embassy official added that this comes "from out of left field--it would be extremely odd that a US governor would not check in with the embassy."

Meanwhile, The State updates its original story with this great tidbit:
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.

So Sanford spent four or five days driving a 2 mile strip of highway?

The 2pm press conference should be.....fun.
