High School. Week 1 - we build a very rudimentary plywood blind on private ground, within cat tails. Cover front and side with cattaild affixed with staple gun. Works well, at least much better than anything a bunch of 16 year olds have thought up so far. Week 2 - cold snap, we decide we need heat in blind, so in High School Ag shop we build a primitive hibachi grill that we can load with charcoal. Next weekend we test and it works. We have heat and can roast slabs of spam with sticks. Week 3 - late start, rush out to blind. Water is skim ice. Leave one guy in blind while two others break ice and put out our entire 23 decoy spread. Tell blind guy to get the heat going cause we are cold. He can't get charcoal lit. We head to blind, spray a ton of lighter fluid on charcoal and throw match. Entire front of blind goes up in flames. So - at first shooting light we end up kicking flaming plywood blind front onto ice and water. Needless to say - no ducks killed that morning.
