I know there are lots of people on the forum that are LE or generally aware of personal safety when in public so I thought I'd ask for some general advice.
I need to go out for fireworks on the 4th, so what are some things you would be generally aware of when you're going to a park-type setting with large crowds. Are there specific geographic features you guys key in on to either avoid or keep in mind in case things go wrong, etc? I was thinking walls near buildings and nearby access to streets leading away from the venue would be nice in case something happens, but is there anything else you'd recommend either as positives or negatives?
