As a MA resident who primarily fishes the South Shore, it is "challenging". When I moved here 18+ years ago, I always just researched parking as much as the area I was interested in fishing. Yes, it sucks that there is resident only parking in some areas, or no overnight parking in some areas, but there's usually a way around it if you can find the spots. It's just always been part of the planning and researching for me. Also, being quiet, respectful and clean, which I've taught my son as well.
