Suddenly, Sloth

Go.Adventure Arenal Park in La Fortuna, Costa Rica, offers zip-lining through the rainforest to tourists. A young boy was the last of eight tourists to go down the line, with park owner and guide Flavio Leiton Ramos following him closely with a camera. Ramos told him not to use the brakes, but the kid did, and rightly so, when he bumped into a sloth! How did a sloth get onto the zip-line? The other riders did not see it, and it would be quite a leap from the nearest tree branches. In any case, the sloth didn't zip away- he took his own sweet time, as sloths do, to climb down the line on his own. They had to wait about 15 minutes for the zip-line to be cleared before Ramos and the child could continue. A good time was had by all. (via Boing Boing)
