Cache is not at posted coords. This is the best spot to start. see below-
Welcome to my first ever fishing spot where i caught zero fish over a few years and lost my entire line that got caught on a jetski as it flew by. This location has a little bit of everything in transportation, trains, airplanes, boats, cars, trucks, bikes. Also has a nice shaded area to relax on a beach chair. During certain months you can see thousands of iguanas basking in the sun along the banks.
