When we have swirling winds while sitting in the bow blinds, we make use of Zebra dung. Place them end to end, and light one side. The zebra dung smoulders, creating smoke which confuses the animals.We had built a brush blind by a waterhole hunting warthog. Lots of game was in and out till mid-afternoon when the wind switched and blew our scent directly to the waterhole and everything stopped coming in. Cris Lorden, the PH decided to experiment so he gathered some dry dung and built a small fire with it. The smoke covered our scent and game started coming back to the water including a very nice pig at dusk that now resides at my house in Michigan. Hecsaid he wasn't sure if it would work but had always wanted to try. I've used that deer hunting a couple of times since and it works.
