I was wondering if anyone could tell me how to get to Point Allerton or some other good sponts in Quincy or Hull.

I take it you are a shore fisherman then.

Try nut island fishing pier in houghs neck quincy very convenient.
Hull has the gut (you must know about that).
Marina bay in quincy, park near the commuter boat and walk all the way out toward neponset river, fish anywhere along that point.

That's just a few.
I'm not sure if the fishing is productive there cause' I'm a boat man. So please don't get mad if you get skunked!:) :) :D

Breal, welcome to S-B... Parking is a bear but work the area of Hull Gut from the windmill & HS east down to the rocky area back near the road... Not all in one night but that's a good place to start... Check out these areas during the day at low tide first to get the best handle on them...
