Great article. I agree... any time you can shoot it can make you a better bowhunter. When the moment of truth comes, it is imperative to be one with your bow, minimizing error.
I've been into archery for nearly 30 years. I'm a VERY good shot at anything under 100yds. But last summer I didn't shoot like normal. Maybe 1x every 2-3 weeks instead of 2-3x per week. Every time I did shoot I didn't shoot bad but not as tight as usual. But I was like "good enough for hunting." I missed 3 deer last season. I've had bad hits before, but that's the first time I've ever missed a deer in my life, and I did it 3x. You can bet I'm going to shoot 2-3x per week this summer. Inside or out; doesn't matter. Just shoot.
