So the second time I spent anytime in Avery County, NC was right after the Blizzard of 96, and I don't recall the exact amount of snow they had there as it varied with location, but it was a lot. My friend had just moved there with his parents, we were maybe 14 at the time, but behind his house was a cleared mountain with a Frasier Fir farm for Christmas trees. After a few days the snow was good and wet, we decided to start at the top of this mountain/hill (probably 3-400') and make the largest snowball we could. By the time we couldn't push this thing anymore it was about 6' in diameter. Someone has a polaroid of it, and I'm going to try and find it.
