My boys love danger. It drives me crazy, and John loves it. Not that sledding IS dangerous (well at least it shouldn't be...), but if there is a way to make it dangerous, they will find a way to do so; like building ramps, going down head first, trying to surf, bailing the sled half way down the hill, etc. They sure know how to have a good time.
We had such a great time sledding, we hope to do it again before the snow's gone.
