I don't carry any designated weapons, but I always have things that would serve the purpose if needed. I've had considerable martial arts training and would suggest all ladies here take at least a self defense course sometime. However, I've never even come close to needing to do any such thing because I'm super careful about when and where I go out. For instance, I'm not a nightlife person at all. Most of my outings are on weekdays. I rarely go downtown and pretty much never to "shady" areas of town. I know it's boring, but I think it's a small price to pay.
