Ok I had another thought. "Canes" but my "thoughts" usually end up costing me money! Not just your typical drug store cane. But tactical, fighting walking canes. I can carry a cane anywhere- federal buildings, government buildings, airports, planes, churches (required in my church-well nearly), bars, sporting events, ect. All the usual places prohibited by federal and state law under carry permitted states and constitutional carry I assume. You don't have to be old, or "rode hard and put up wet" like me. ADA prohibits even security from inquiring as to why you need a cane. With some training these things are deadly. I don't see the cane as a substitute for a handgun, but in addition thereto. A strike with a cane could give me additional time to get to the gun at bad breath distance for example. Additionally it gives me another option to using deadly force although a strike to the head with a cane can be deadly force or very serious permeant injury. My hobbies besides shooting handguns and playing a mandolin badly is visiting my orthopedic Dr about every four months for whatever body part isn't working or not working without significant pain. It's been the knee, trigger fingers, shoulder and currently the right achilles tendon. Additionally due to most of my back being fused (T4-S1) and having a brain (yes I have one despite comments to the contrary by She Who Must be Obeyed) bleed stoke, I use a cane from time to time. But legally one doesn't have to prove that. If interested I refer you to American Cane Self Defense by Dr/Grand Master Joe Robaina for examples of training and canes he designed and made by Cane Masters, and to Cane Masters for a head spinning number of canes and some training videos. Just something I've had thoughts about-well "obsessive compulsive" as I've ordered a cane designed by Joe Robaina and made by Cane Masters and sighed up for his six weeks online Zoome training twice a week. The cane is like a gun, just having it isn't a replacement for training. BTW the average age of Joe's students is 68. I'm 77 and some of his students are in their 80s. Both ACSD and Cane Masters have a number of short YT videos. If interested here is an example of an informative video by Dr/Grand Master Joe Robaina . Now I got to quit thinking or it will cost more money.
