Josh, you are more likely to be involved in a violent crime in rapid city, sd than you are in the springs. Stats won't help, but here's something I did when I was in college. I walked up and down the 'roughest' neighborhood that I knew of and could reasonably find (the end of bards town road in Louisville, ky) and I didn't feel any fear or worry because I knew I was prepared.

i was young and dumb then, but here's the point. I know what a troublesome area looks like, and I simply avoid those places. Keeping your mind on an amber state (aware but not alarmed) is what helps me walk around the springs. Stay alert, brother.
