I've been a few hundred meters from my tarp and couldn't see it. That was open ground looking down at it knowing it's there. Even my blue bivvy and mate in his black one could not be seen. You'd be surprised what you can get away with. There we're 4 of us in 4 tents camped in the corner of a lakes field a mile or so from Keswick and a field over from a farmhouse. We had a gd night without problems. Not to be recommended but it was a long day and we'd had a few at a pub on the way so couldn't go any further.
