KimPossible, I've been a lifelong walker (my mom didn't drive & dad was in the Air Force away from home a lot). While walking, I have had a car load of guys stop & demand I get in or they would shoot me. I gracefully declined and said "You'll just have to shoot." I walked away with no consequences. I have also been tapped on the shoulder while walking and asked for the time. When I turned around it was a guy dressed as a vampire - not Halloween either. The list goes on. There is always danger. I usually laugh it off and go my merry way, but stay alert.
I was stopped while riding my bike by a guy in a van asking directions. I immediately went around to the middle of the street & rode by saying - "Don't know." I felt danger so hightailed it out of there. Trust your instincts. I don't carry a weapon but tend to run/ride fast if I feel creeped out.
