I go to costa rica frequently because I know people who live there. I was there this past week and saw that the property is near many rivers. Now my mind is set to go fish out there, but I don't even know how or what kind of fish are in there. This is in the middle of the country not near any coast. These are pretty fast moving shallow rivers, but there are sections with slow parts. I'm assuming I need to learn how to fly fish? Any one have any experience or can lead me in the right direction? I've seen locales fishing before but didn't get a chance to ask anyone. I don't speak Spanish anyway
