Colonia De Sacramento, Uruguay ? While President Bush did the talking, the first lady did the walking.

Laura Bush played tourist Saturday on a foot tour of a UNESCO World Heritage Site, the ruins of a 17th century Portuguese fort with a view of the River Plate and Argentina on the opposite bank.

The first lady strolled down cobblestone streets of the old town of Colonia de Sacramento. Uruguay’s first lady, Maria Auxiliadora Delgado, escorted her.

A huddle of ochre-colored and stone-built buildings, the Colonia historical district set alongside the ruined ramparts here is a famous tourist draw.

Laura Bush also visited a lighthouse and souvenir shop as a tour guide and translator accompanied her.
