Huntnma and I were out a couple years ago when this guy stalked our decoy and almost shot it.He went to raise up on it and we both freaked.We had been whistlin' but he either didn't hear it or ignored it.Thankfully we had our orange in the vests.After that I don't go onto public land without it.It may be a pain and not required but it can save a life or two.Definitely worth bringing.
