Alumbrado Navideno ...

... famous around Colombia, it's a competition where cities deck out their rivers in festive light displays. Medellin's display typically wins, not surprising since their display seemingly runs forever along the river. We were surprised at what a big deal it is - it was a lot like the Calgary Stampede, with food and beverage vendors stretched all along the banks of the river, and was completely packed with people. Great carnival atmosphere, but sans the rides.
