This is a fundraiser to raise money for worthy causes.
Here's some more information about it:
These funds will help park rangers here in Tortuguero National Park to purchase essential gas for boats used to prevent Sea Turtle poaching. While the cost of gas has gone up, the Costa Rican gov't budget for it has gone down. Every night on Tortuguero beach, beautiful and gentle Green Turtles and Leatherbacks struggle ashore in order to nest and lay their eggs. They are vulnerable to poachers who will either kill them for their meat and shell or steal their eggs. Please help in any way you can.
Please support the organizer's efforts by donating to one of the projects below.
