Peter,
I live in Brewster. We trailer so we like all Cape and island waters, including Long Pond, plus Boston Harbor, Lake Winnipesaukee, as well as trips to Canada and Florida.
The drink holders there are not bad at all for fishing. I run two boat roads out of them for trolling. Obviously you can't use them for giants, but if you watch them carefully you can catch big fish.
And you? Where do you boat and fish?
Peter
