Glow in the Park benefits Fairmount Park

PHILADELPHIA (WPVI) -- If you saw an unusual glow coming from Fairmount Park Thursday night, there was a good reason.

This is called "Glow in the Park".

Hundreds of people showed up to the Smith Memorial Arch for a night of dancing, drinks, and food.

This is the fourth year for the event.

It benefits the Fairmount Park Conservancy.
