I live in Miami and take the Metrorail to get downtown. This puts me in close proximity with some questionable characters. Every 4-6 months a situation will arise with one of these sorts where a fight almost occurs. I am 68 and truly look my age yet some younger moron will start acting belligerant without my having caused anything. What does the gang think about my carrying and using mace should the situation call for it? Or would my doing so escalate things in a way not beneficial to me?
