Sometimes, going into courthouses, DMV and other restricted places, you just shouldn't and can't carry. Same applies if you want to drink hard liquor or any liquor for that matter while dining out, carrying concealed will risk losing your CHP. As of late, I have been training in the martial arts defensive cane use. As I said before, I am 80 years old. No leg speed left; but, my hands and arms are still fast and strong. A good stout hardwood cane of 1" thickness is an awesome weapon when used properly. I can take it anywhere, even on commercial airlines. You can pay as little as $9 or $300 for a "fighting" cane. They all work if you devote as little as 1 hour a day to practice and hone your skills. I still practice my karate and kung fu forms which have been with me from childhood. However, adding defensive cane fighting skills after passing the age to collect social security has enhanced my defensive options. A cane gives you much better stand-off distance chances of delivering disabling blows; and, devasting close-quarter power strikes that easily break bones or effortless leveraged take-downs. There are many UTube videos to demonstrate the effectiveness of canes. Most states consider martial arts tools such as nun-chucks as deadly weapons and classify carrying them concealed or openly as a felony. I know of no such laws for a "walking" cane. I am ever vigilant when out in the streets at my age, particularly in parking lots. You cannot always maintain a stand-off distance, particularly in busy areas like shopping malls. A stout cane carried without a limp is almost as effective as open carry and no one calls a cop on you. Suspicious characters will always size-up a potential victim like any predator will do before attacking a prey. When they see that stout cudgel, they wisely look elsewhere. My handgun is always my last option, although I am glad it is there. I will settle for my cane in a knife fight; but, against a gun...not so much. That said, I can deploy it much faster than my gun, because it is already in my hand. If the perp is up close, then the cane may be the better choice, yet.
