The Tropic of Capricorn is named because about 2000 years ago the sun was entering the constellation Capricornus on the December solstice. Now the sun appears in the constellation Sagittarius during the December solstice.
But, really, the great thing thing about this line is that it isnÂ´t just an intangible point of reference…it means we are OUT OF THE TROPICS! Since Central Mexico, everytime we dropped in elevation we have been greeted by a high temperatures accompanied by heavy humid air and insects.
Now we are pedaling through an early Argentine spring and the weather is beautiful…a rarity for RTS.
