Years ago when I was stationed at Otis AFB (Pave PAWS) I loved to go swimming this time of year.
The tourists were mostly gone, and the water was warm. I usually would go to the closet beach, which for me was Sagamore or Sandwich town beach.
I never once saw a seal, and I fished year round, had a shell fishing license for mussels and clams, and swum a lot in warmer weather. I left in December of 1982.
Things have changed. The white sharks are protected and the seal population has exploded.
Below is a quote from my website newenglandsharks.com
Since white sharks do kill and eat seals, and we are about the same size as a seal; if you are in the water with the seals, or near them, bad things can happen – bad things have happened, and will continue to happen. Let’s face it. Sharks happen! In 1997 the white shark became a prohibited species to help increase their depleted numbers. They are making a comeback, so expect more whites in the New England area.
After all they belong here, this is their territory, and their territory begins when the salt water gets above your knees. - Tom
