Sounds like you have put some quality thought into your efforts and plans. One random though that went through my head was have any of your walks or hikes been at night? Learning to move safely using ambient light takes practice. I hiked several miles to watch the fireworks on the 4th and could not help but notice how poorly most people move in the night. For those who might think I had forgotten my EDC and did not have a light you will be relieved to know I had at least 4 with me but only used one once to light the way for some lady that was about to fall in the river. I prefer to enjoy the night unless its cave dark out and have found it a valuable skill more than once.
