Will You Go To An Outdoor Concert?

There are a lot of people asking a lot of questions in the aftermath of the Las Vegas shooting.  One thing that dawned on me was whether I would go to an outdoor concert like this in an area where there are so much is uncontrolled like buildings, etc.

At a venue like DTE you hope that security will do the job including limited/controlled entry into the property.  I worry about copy-cats who might try and duplicate the carnage at some other event taking place in a city setting like the Route 91 Music Festival.  So the question is: Will you go to an outdoor concert with similar logistics?
