Ice baby
Don't you just love 7 year olds? They're so full of energy and the desire to prove themselves useful. It's a handy way to get a clear sidewalk.
I tried to make a looping slide show that would show Isaac in action on that walk, but I think my free Google Picasa ap' is just not adequate for the job. That's o.k. I still love Picasa. You can live with a measly little movie-ette can't you?
