Sounds like when we were kids. Have a snow ball fight. Part-way through use the shovels as a shield. Get it hard in the face with a snowball. Go after the other kid with your shovel.
I got hit in the face by a hose nossle too during a “water” fight.
When the family Christmas tree was discarded, we climbed that hill with a jug of hot water in hand to bore a hole for the tree. Once thrust into the hole, the water would freeze around the tree making our territory.
Every day after school, we would race home to protect that tree, the hill and our territory. My kid brother and a couple of our friends could hold off at least five times as many kids from the high ground. We would rain down snowballs on any who attempted to climb that hill and dislodge our tree.
One day, the opposition decided to get more organized. There were probably 30 or 40 kids headed for our hill. We got out the garden hose and sprayed down the hill. It was a load of fun to see them all get partway up the hill and go sliding down. We warned them that the next attempt to take our tree would mean spraying water directly on them, not just the hill.
Even a North Dakota kid is not going to risk getting soaked when the temperature is -20 or so and they have a long walk home.
