What ocean can ashes be spread over in pa by boat?

Other answer:

burnieob:
The Delaware River and Bay lead from eastern PA to the Atlantic…..about a hundred miles from Philly.

The Susquehanna area drains into the Chesapeake and two hundred miles later the Atlantic.

West of the Alleghenies, rivers drain into the St Lawrence River , then the Atlantic in Canada; others drain into the Ohio which ends up in the Gulf of Mexico.

So your answer is The Atlantic, but not directly.

STEPHEN:
IN PA? There are no oceans IN PA. Once you get outside PA you can spread ashes over any ocean you want.
CMV:
On this planet we have these things called maps , you see .
Greywolf:
The Atlantic. No other oceans are available in PA.
