George Shillinger, Hopkins Marine Station, Pacific Grove, CA -- We're keeping our eyes on the four remaining Great Turtle Race leatherbacks whose satellite tags are still transmitting: Turtleocity, Genevieve, Freedom and Billie. In case you're new to TOPP, we co-sponsored the Great Turtle Race last April, in which eleven leatherback turtles "raced" from Playa Grande, Costa Rica, to the Galapagos for 14 days.
