If you haven't already, I strongly suggest getting a recorder. Preferably one with a slide that locks the buttons so it doesn't turn itself on and off in your pocket. Leave it on at all times when open carrying or learn to operate it quickly, reliably, and discreetly. If, like mine, it burns through batteries you may want to keep spares in your vehicle. In the unlikely event that you're harrassed by police it can prove invaluable. Just my $.02.
