If I come up on a scrape or rub, and have the need to relieve myself, which is usually a hassle with Scent blocker pants base layers, boxers, and my leafy gloves, I will pee on it too, and then take my buck bomb detonator with doe in estrus and add a few drops in and around it. Every time I have been back by the scrape or rub...the scrapes are torn up and obviously seems the buck is pleased that his mark was visited. who actually carries a pee bottle with them? I wouldn't put it in my pack, pocket, or even want to deal with the extra accessory to carry. I have too many gadgets that work to get me a deer to carry, and if it spills on me, it turns into a scent mask!
