Yeah I know that, but some neighborhoods would complain about throwing snowballs at their houses.
I've seen that happened long, long time ago when I was 10 years old. I did do the same thing throwing snowballs at each house, some people got upset. So I decided to stop throwing any more snowballs, or else they would call my grandparents.
Even, I did make a snowball and put a small firecracker on top of the snowball, then lit it and throw it up in the air and it blew up! BOOM!
