I've not shot the 3D course at Cheyenne Mountain yet but their known distance range is very nice. AFA has a fantastic couple of 3D courses on campus-- lots of up and down, partially screened targets, targets angling to and away from the shooter, etc. etc. Much to my chagrin (and Bill Pellegrino's likely delight), most of the backstops are rock and not too friendly to carbon arrow shafts.Good of you to join us. I hear good things about the 3D range @ Cheyenne Mtn State Park.
