Is it safe to attend an evening concert by yourself? Parking lot and such?

Yes, it's well lit.

Parking lot have lights and the Philadelphia police are also there

Yes. Security and bag check and bright lighting around the area.

Yes.

Yes! Well lit, and plenty of security presence, without policing over event-goers activities. Was a fantastic night! I hope I get to go there again

Yes I was there about 2 or 3 weeks ago and its completely safe because it's all outside they have a roof you can sit under but its fresh air the entire time

In the parking lot, yes. But you would do well to arrive early and get a good spot.

Yes there are lots of police and security, they do a great job.
