We've got some spots where you don't need a boat or kayak in order to experience some pretty good fishing. Just a couple of hours south of my home in Sarasota, I fly fish spots along Tamiami Trail by foot. Best spot is off Loop Road.
We use 3- and 4-weight fly rods, floating lines, 7 1/2-foot leaders and Myakka Minnows. We catch mostly oscar, but also Mayan cichlid, largemouth bass and bluegill. It can be a hoot.
It's also very good when it's too windy to fish elsewhere.
One warning: please take a careful look before you get out of your vehicle. Alligators like to lie in the sun along the road during the winter.
Not only is the fishing good, but the scenery is great.
