Chris, that's what I have in mind. The wood behind the target is for the roof. I'm making it hinged so that it will swing up and lock in place for added protection. But you are absolutely right, I need to do something about that gap on the left.
Maybe I can hinge some side flaps on this thing and turn it into some kind of a Transformer toy. One minute it's an innocent looking yard bin, the next a nifty sand target able to stop thousands of arrows. LOL...
I also need to pretty it up a bit so it isn't such an eyesore. I'm just happy that my wife shoots too. She's only shot into it a few times, but loves it.
Thanks for your input. I really appreciate it.
