If you've been in the ocean deeper than 2 feet of water, anywhere in the Gulf of Mexico, particularly during May through August, you've likely been within a hundred feet of a shark, if not much MUCH closer.
A few of my catches:
All were caught within 100 feet of shore, in less than 6 feet of water.
This is what I want to go after, but I really need a kayak for bait placement(and I need to be there in summer when big sharks are more abundant close to shore):
That particular video was taken on Sanibel, where my grandparents spend the winter months, and where I get to swim regularly.
