On one winter camping trip with my youth group we decided that we wanted to start a snow ball fight with another group that was also camping there, because that’s what bored teens do.  So we worked out a strategy; some of us attacked their camp and started the snow ball fight and got them to chase after us.  The rest of our group was emplaced on the top of a hill with a large supply of snow balls already made.  So the runners lead the other group into our well laid out ambush and with our planning we were victorious and kept them from attacking our Cabin In The Woods.  Since there is no point in starting the snow ball fight if you don’t plan to win it.
