Went down to PA for a 2-day meeting this week, at a location about 45 minutes north of Philadelphia. On Wednesday night, I drove into Philly intending to take some nighttime city shots of buildings, the skyline, etc. I was surprised to see a complex searchlight display over the city when I got there at around 10 pm. Turns out it was the final testing for Open Air Philadelphia, an interactive art exhibit running 9/20 - 10/14.
