I know what you mean about flagging tape..or ribbons as I like to call it. I hate the stuff..espicially when someone comes in an area I've been hunting and puts it everywhere. I think some hang a strip on their truck door handle to make sure they get back to safety beforethe bugger mangets them. You can't see that stuff at night..it's for people who are afraid of the dark and come in and go out during the day.
Nothing is worse than being back in the woods, up a tree and having to look down at plastic ribbons hanging everywhere..it reminds me of being on a construction site.
I don't have a problem with using it in rough places, but take it down while figuring way in and out..it just attracts attention from others anyway.
