The seal population is unbelievable. The seals have spread around into the Mass. Bay side, and we have white sharks showing up here and pinging the shark buoys on a regular basis.
The buoys are placed close to shore from Scituate thru Marshfield and to Plymouth. Only the tagged sharks can ping the buoys, so untagged whites are around but go undetected. -Tom
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.
