I was the assistant Fencing Coach in grad school. One day while walking from class to the gym for practice with my fencing gear in its special carry bag,, I was stopped by police in a car. "Are you carrying a weapon?" they asked. "Yes," I replied. "Would you please show it to us?" (This was in Kentucky and they were very polite, but I could see they were on edge because of all the protests around the country in the 1960s) So I pulled out my fencing foils. One of them wanted a fencing lesson right there and then.
Oh, and walking after fencing practice I had to go through a park to get to my bus stop. Other college women had warned me about danger in that park, but for some reason, I was never accosted. Might be because I was carrying a 'weapon?"
