Yeah, I have seen them also! Pretty cool...wreak havoc on the fish though and fihsing becomes non existent when they are around. They are as fun to watch as the dolphins, but can scare the you know what out of you when the pop up in a wave or on the beach right next to you.
They usually venture down here when it gets cold, but the water is down into the low 50's already so...
Last winter there were several young ones that came up in the Toms River Twp Section of the Beach that were injured and/or ill and were rescued by the Marine Mammal Stranding Center.
