Safety Activity Checkpoint for Tomahawk/Axe Throwing on page 159 has been updated with this additional statement from GSUSA: For a four lane range, you need one trained facilitator or instructor plus one additional adult that is familiar with the range watching the throwing line. There then needs to be additional adults to meet regular girl-to-adult ratios for girls not actively on the throwing line.
