Making a snowman is a great winter activity. It gets you outside and can really be a great workout. Last weekend, we spent two hours making this beauty--which is indeed over 6 feet tall.
The process is simple--so long as you have snow that will stick to itself. You just start a little snowball and start rolling it. You can actually make a snowman with a small amount of snow (inch-wise) if you have the square footage to do it. Or acreage. After we were done, the kids were tired and my arms hurt.Great winter fun!
You also might enjoy licking your giant snowball. That can be fun, too :)
