Blanket of Purple

This is another field of purple flowers I shot this spring and I remember this spot well because I walked at least the length of two football fields through here looking for good shots. The problem was when I got back to the road which is where the trees are,I noticed my polarizer was no longer attached to my lens. It is a 77mm filter which runs about a hundred dollars, and as I turned to look back across the field I could barely see anywhere I had walked? Well I figured it was a lost cause,but after about five minutes of walking, I spotted it among the flowers.
