I live and surf Nantucket in the summers. Having grown up surfing on the Gulf and on the pacific side of Mexico, I have always been near and around sharks, especially in the river mouths. When fish run, there is something chasing it. I will still surf...but I have noticed that the seals are curious and becoming more comfortable being near us in the water. The seals are feeding. I wonder when the Whites get the memo that there are seals just hanging out.
