For more than 40 years, I’ve fished for big Florida Keys tarpon from early spring through summer in my backyard. I never go about it nonchalantly. I most always have a personal goal in mind. Not just to catch fish, but like most dedicated anglers, to take a bigger one than the last time. Say, a silver king that would tip the scales at 100 pounds or more, on a fly rod with 6-pound-class tippet, or perhaps a baitcasting outfit spooled with 6-pound-test line.
