I guess the drop off depends on which coast. Tamarindo is on the north Pacific coast of CR. The drop off there starts about 7 miles out and drops from 400' to over 4000' in roughly a mile. Talk her into 2 days of saltwater fishing; you won't regret it. Where are you staying?
Oh, I have to go fly fishing, so I'm debating between Guapote in FW, or checking out the saltwater flats scene for Monster Tarpon. I dont know if Im ready for a Silver King that big on fly yet!!!!!!!!!!!!
