Ya know, when I was young and just starting to bow hunt, every hunter with any amount of success always would say a few things in common. Things like, don't draw attention to yourself, don't draw your bow when you can see their eyes and don't shoot when they are looking at you. Nowadays, all those things are standard procedure in the hunting video's. I think you probably did things just about right depending on how fast she was going. Lots of guys prefer to shoot at a walking deer over a standing deer and claim they are less likely to duck the string.
Sounds like you had a blast and I bet you have it on "video" in the old hair covered computer to replay for the rest of your life.
