Places to wet a line close to Providence?

[Elmo]

Hey Gents,

I will have a few hours to kill Thursday night when I drop my daughter and a friend off at the DD center for a concert. Any areas fairly close to there to try wetting a line without too much trouble with parking, access, etc... Also, a MA saltwater licence is valid in RI correct? I think I read that somewhere. Itching to make some first casts of the season so any insight is appreciated. Tx
