By the mangrove bushes at the southern edge of the park runs a little catwalk. Beneath the catwalk are the fast-running waters of Biscayne Bay. A low bridge just to the south blocks boat traffic, while the currents bring baitfish through. Waiting for the baitfish are any number of lunkers, snook, tarpon, snapper, sea trout. And you're standing over it all, literally and figuratively atop the food chain. A beautiful green park behind you, the colorful winding bay in front of you, and all kinds of possibilities beneath you.
