I didn't think the seals were much of a factor this past season, as I ran into much fewer than in the past.
The closing of the southway channel forced them away from their usual haunts at the tip of south beach.
I've read that many migrated to north beach (Nauset)but in my experence this season there was no large pods that followed you as you walked the beach, looking for that easy lunch.
Maybe I was lucky.
