Cal and I have been shooting A LOT of archery. I got my first Robin Hood last night at 20-yards in the backyard. It went straight in, you can see bits of the first arrow's plastic nock jammed in there. I've chipped some nocks and shot away some fletching but this was a nice surprise. If you shoot enough, odds are it will happen. After that, we shot at some apples, golf tees and $1 bills, I tell Cal he can have the buck if he hits George Washington's portrait. Its cost me a few dollars but its a powerful motivator.
I saved the arrows. You only get one first Robin Hood, hole in one, 25 (or 100) straight, etc...
