Just look around the ground next time you are walking by any road or highway. I don't see any nips on my rural street in S. County but as soon as I hit the end of the street and walk along the country road there I can find 3-4 nips before I make it 100 yds. It's shocking how prevalent it is and is by far the most visible litter on the side of the road down here at least. You could walk 2 city blocks in distance and probably pick up 50 or so of them easily. Even worse by stop signs etc.
