I recently took up hunting again (wild pigs in Texas), and while I've been a serious backpacker since 1971, I never owned a poncho; never saw the need.  But now, I find that using one shields me and my rifle from the rain and wind and, at the same time, provides excellent camouflage.  I've used the tie-out points to lash it to trees as a quick shelter in 30mph winds - with no tears.  I'm now buying it as a gift for friends who also hunt.
