Sheryl,
I feel your pain. Nice to wish and another to do. In my childhood I too was chief pooper-scooper every time I visit my uncle's farm. He had 2 cows. I always took home a bag of old composted manure with me. Memories are better than reality. We would fill a old dog food bag called 'Chunks of Joy'. After my mother would always laugh at the thought.
