Stop in for a cup of coffee

And, just for anyone who doesn’t know about the Delaware river...

The Delaware river drains an area of 14,119 square miles (36,570 km2) in five states, New York, Pennsylvania, New Jersey, Delaware and Maryland. Rising in two branches in New York state's Catskill Mountains, the river flows 419 miles (674 km) into Delaware bay where its waters enter the Atlantic Ocean near Cape May in New Jersey and Cape Henlopen in Delaware. Not including Delaware Bay, the river's length including its two branches is 388 miles.

The Commodore Barry bridge that spans the river near Marcus Hook Pa to New Jersey (near me) is 13,912' abutment to abutment making it the longest cantilever bridge in the US and the fourth longest in the World.
And if I recall my experience correctly, It's free to cross the bridge into Jersey, but you have to pay to get out!
