First off, I want to give props to you for not taking a shot at that deer, knowing that it was a bad angle. It would've more than likely ended with a wounded deer, that you would never recover. And secondly, I had the biggest buck I've encountered walk 42 yrds from me last year, only to veer off the trail and stay in the edge of the pines. Never got a shot at him and never regreted not having a rifle( I only bowhunt). It's part of it and it makes me a better hunter. I get to sit and observe travel patterns and everyday behavior. Learning a deers body language if invaluable. Here's the one that got away from me last year.
