Video - Flying High in Costa Rica

Word has it that humans really can fly...and here's proof!

Well...not quite. But it is April Fool's Day after all.

This video was taken by a guide on the Arenal Volcano Zip Line during a recent Smithsonian Journeys trip to Costa Rica. Don't miss the part where he turns upside down, about 30 seconds in. Traveler Werner Schaer was kind enough to share.
