As a very young lad, I recall riding on the trailer covered with feed bags, towed by a Farmall tractor as my grandfather drove around the farm feeding his stock. To open the feed bags, he would pick at the string for a few seconds and then Voila! The bag would be wide open, the string went in his pocket. I just assume, somewhere in the barn there was a candidate for the world's largest ball of string.
Fast forward to 2010 and I find myself with 100 bags of coal and a struggle to open the damn things.
Here is the secret and it works like a charm. http://www.motherearthnews.com/Sustaina ... ysack.aspx
