Philadelphia has a fantastic fireworks display.
Obviously one on the 4th of July in addition there two others that are pit on by the Philadelphia Phillies baseball team.
All three are fantastic.
The 4th of July display is right on the Delaware river. Several marina's in the immediate vicinity.
The Phillies fireworks display can be seen from the river. They are walking distance from the river.
I am always aware of safety and security. You will not be disappointed or unsafe.
