I did not have one. Never thought to have anything and in my stupidity, never thought I would be in a position to need anything. Last week a guy in a hoodie approached our table while sitting at my favorite Coffee Place. Now this all happens in seconds. I did put my cane up but found I have no capacity to swing it and hurt someone. He stole my new Android Cell Phone off our table which I had had for four days. It's a pain replacing the numbers and closed caption capabilities but with diligence it can be done. Fortunately, I don't use a Cell Phone to handle my life but my PC. My carrier turned off the phone immediately, however, he will probably sell it for parts. Had two insurances on the phone and in the end made $200 dollars and phone replacement at $100.00. The end of the story is I am now the proud owner of Pepper Spray which I think I can use and a Taser. I found my self unable to inflict damage with a cane.
