We went to Brazil for the weekend a few weeks ago for Alex Pommez's wedding. Not quite a weekend trip but pretty close - I arrived on Friday afternoon, Alicia arrived on Saturday afternoon, and we flew out Tuesday night. We had hoped to get later flights out (had to change the tickets a few times as a result of moving from HK to SF, and Alicia's acceptance into the Fletcher GMAP program) but it didn't happen. So we had a few days in Praia do Forte, the Brazilian fishing village where the wedding was held, and then a day in Rio, all of which we spent walking around the city. You really can't see all of Rio in a day, but I think we came as close as is humanly possible.
I took some photos, which, while not technically available on this website, are available on the web through Ofoto. Mostly photos of people from the wedding and whatnot. You can, however, see the village church with the local kids watching from the doorways, and the house where the Pommez family had the reception and a Sunday 'lunch'. I particularly liked the security guards lurking in the background on the beach side of the property - really made it feel like South America.
