Tropic of Capricorn

We road through the Tropic of Capricorn today.  We are now heading back south so this is our second time passing through it. In the US Coast Guard there is a ritual that when you cross a Tropic or the Equator.  AL and I agreed we will not be doing any rituals. I may make myself a google certificate.

The Tropic of Capricorn is the dividing line between the Southern Temperate Zone to the
 south and the tropics to the north. The northern hemisphere equivalent of the Tropic of 
Capricorn is the Tropic of Cancer.

 In South America, along the tropic, the east side of the Andes receives warm and humid air
 from the Atlantic Ocean. As a result, areas in Brazil adjacent to the Tropic are extremely 
important agricultural regions, producing large quantities of crops such as coffee, and the 
natural rainforest vegetation has been entirely cleared. In and west of the Andes, however, the Humboldt Current makes conditions extremely arid, creating one of the driest deserts in the 
world, so that no glaciers exist between Volcán Sajama at 18˚30'S and Cerro Tres Cruces at 
27˚S.^[4] Vegetation here is almost non-existent, though on the eastern slopes of the Andes 
rainfall is adequate for rainfed agriculture.
