I remember doing that with a couple of my buddies when I was a kid, I only had 2 boys my age to play with which was just fine for a tom boy. We were going to make igloos, but that turned out to hard so we went with fort walls. And when did making snowmen get so hard? They were simple when I was a kid, but I started out to make one a couple of years ago and found that to be way too much work! I bet your grandsons had a ball!
