If you are concerned about protection on the Trail I understand that a can of nwasp/hornet spray is very effective. It is more effective than pepper or bear spray and it is more accurate. It will shoot a stream of 20 to 30 feet. It will kill a snake or a mouse and will stop a bear in its tracks. And unlike a gun it is legal in national parks as it is not considered a weapon. You can just say that you are allergic to wasp bites. A can will weigh a little more than a pound. X-man
