I like to go to my archery range once a week. The archery shop I am going to has a 20 and 30 yard range with 3d targets in addition to the big wall targets in the back. I'll set some of the 3d targets at different yardage intervals to test my aiming judgement from shot to shot, but repeating this after a while does get monotonous. For fun and practice with my 45 lb recurve I am wondering if anything anyone has any suggestions on how to spice up a days shooting or add some shooting challenges while at the range. Any suggestions?
