Sand Creek is probably the prettiest 3D range I've ever shot. I bet it's going to be beautiful and a blast on Sunday. They have great targets that are in good shape and you'll be challanged in your shooting. My family and I try and shoot as much as we can there. Plus you may just see the real thing as well. I've seen numerous deer while walking the course. Some as close as 30 yards and some big ol bucks as well. I know there is a healthy turkey population running around too.
You can also click on the Sand Creek ad on the side of the page as well. That will get you there.
Good luck to all on Sunday. I may still try and get down to shoot myself as well. About 50/50 right now on if I can get stuff done to free up the time
