My first post from Costa Rica is a farewell to the first leg of my trip.  This morning, at 4:30 AM, Allison and Erin climbed into a taxi for the airport, and so ended our three week excursion to the Osa and premontane rain-forest.  I find it fitting then to post a picture of the four of us posing atop the first cascade of several in a river we dubbed Rio WTF.  The river’s original name (Koyok) was immediately revoked when we realized that we would need to climb two waterfalls and a mountain to collect leaf samples from it (Mike and I were able to do it in under 10 sec with minor injuries).  If you’re not aware of what the new name’s acronym stands for, google it.
