I have a lock-in at my Parent's place that is about 20' up. I started shooting from it about this time last year. I have a Cobra Viewmaster Pendulum sight. I took a few shots this weekend and WOW! Dead on at 10, 20, and 30 yards. What a confidence builder. I also slipped a couple broadhead shots in there. The old SlickTrick grouped right in with the fieldpoints.
Thank god for kids.
