Kid-friendly Crabbing locations near Boston area?

[Hong1005]

Good morning and happy Saturday!

I'm trying to get my kids into handlining and I'm wondering if there are any decent kid-friendly crabbing docks or locations within an hour or two of the Boston area (preferably south of Boston). My daughter, who is 11, is determined to bring home crabs and cook them, so an area with a decent population of keepers would be ideal.

Any and all tips appreciated!
