...huh, I pack some little cheapazz waterballoons. Work pretty good for marking things, too. Surprising how far you can spot a bright colored balloon tied to a limb, a piece of sage brush, or even a clump of grass, better than ribbon @ a distance...
Been using it for 25 years. When I started hunting the "wet" side of Oregon I had an incident sitting on stand for two hours in the rain and holding my rifle in the barrel up position . Luckily I didn't fire the rifle but when I opened the action to unload I was amazed at the amount of water in the chamber/barrel. Taped the barrel ever since.
