The best place to shoot archery... Is any where hosting an event! But seriously... The best places to shoot are the places that set a course to challenge you rather than the places who set easy courses to stroke the shooters ego. You will get better by challenging your abilities, not knocking the bottom out of 3d targets at 20-25 yards over and over again. Any course that uses hills, timber and any other topography to challenge you the better.
I shot yesterday and one of the targets was a turkey facing me on pretty steep downhill shot. I enjoy shooting the more challenging targets more then the simple straight forward ones.
