I hunted with both jcfd2201 and Randy back in October. I had never heard of the Nutsaver, but, well, it is just that. It worked great and was something I had never heard of or though of using. We crossed many fences with it.
I suppose there are lots of other things out there that could be used. Whatever works, works.
Also, I think having one of these, of whatever material you choose, is a good idea - just as long as it's thick, which the Nutsaver is. It also depends on where you hunt and if fences are an issue. If there are fences to cross often, then this thing or something similar is one heck of a good idea.
Just an added note for the heck of it, Brian ( jcfd2201) and Randy are really nice guys, very accomodating and downright enjoyable to be around. Thanks guys for showing me a great time in Arizona.
