I set up the archery range for our local scout camp a few years ago. Contact the BSA Council office in your district. They have a outline for what you need to do in order to make and run your range safe. As for your bails, I just stacked then 2 deep and 3 high at 15 ft for Cubs, makes it easier for them to hit it. I also covered my targets completely with ballons so they got a extra bonus when they hit it. Takes the pressure off of trying to get a bulls eye. The regs will tell you how far you need to set up for Scouts to get their Merit badges...Was the best time of my life...Have fun
