When February brought an unseasonable amount of snow to Knoxville, the neighbors invited us down for an afternoon of igloo building. What started as a neighborhood project quickly turned into an endurance and speed test for 4 of us, trying to get it finished before the snow got too cold and unworkable. It was an epic success, and provided several nights of good sleep to both boys and men. Highly recommended, should you have the right kind of snow land in your back yard!
Great lesson in engineering, cooperation, hard work, and group design. Not to mention the exercise of hauling and lifting wet snow!
