Used to work for a company where the owner was an avid sports fisherman.
Each year, he would rent four boats in Boca Grande along with several rooms at a nearby motel.
Then he would divide the company into 3rds and send each third down to fish for a couple of days during tarpon season.
Tarpon are not little fish, and we used 85 lb. test braided line.
I remember when I caught my first tarpon. It felt like I hooked a greyhound bus.
Felt like my arms were going to get pulled out of socket.
Since we weren't allowed to keep the fish, we could only reel them close enough for an estimate of size.
There is a rule of thumb they use to estimate weight, and they calculated my fish weighted about 145 lbs.
Unfortunately, the following years had so many sharks in the area (hammerhead and bull sharks), that any fish caught were ate almost instantly (amazing how fast a shark will consume a 140+ lb. fish).
