I lived in Aurora (next to Stapleton) for two years in the late 70's while in college and that whole area was touch and go. Colfax Ave was lined with strip clubs and apartments in that area were "low rent" in every sense of the word.

But the "personal safety" lesson this young man has had to learn is also a strong reminder to all of us everywhere we go, especially on trips. All this cost cutting directed at air crew has placed us all at increased risk. We can't even carry pepper spray anymore, so my advice it to learn how to "use your hands" for your defense, should it come to that.

It's really not that hard to learn, requires some practice, and may make the difference one dark night. Some close quarter combat knowledge is also a good idea for crew while on the airplane. I know the company is supposed to hit on this stuff at recurrents, but most are simply checking the box. Check with a local martial arts school and pay someone to train you, it will be much superior to anything recurrent has to offer.
