Today was I was in a large Home Improvement store and in the flooring section I saw these cool little 8” by 8” pieces of carpet. Right when I saw them, I could see myself lying on the ground at St. Leon, Indiana, looking in the butter shale for trilobites and complaining about rocks digging into my elbows. I will place a couple of these in my pack when I collect. They don’t weigh anything, can be used for my elbows or knees and the best part is- they are FREE.
