Tracker, 
Not sure about Golden, west Denver area. Call CPW (Colorado Parks and Wildlife), there are several indoor ranges in that area, as well as outdoor, I think .  Bass Pro shops and Cabela's may also have info.  Roy Poole is a Hunter Ed instructor and I think has his own shop, I will pm his contact info.  Further north Archery in the Wild in Longmont has an indoor range, and I think there is one in theThornton, Westminster, or Broomfield area.  We are in Loveland, up I-25, Big Thompson Bowhunters maintains an outdoor range at the Lon Hagler State Wildlife Area(SWA), with free public access.  Exit 255, then west about 7 miles to County Road 21, left(south) about 1/2 mile to the road back to the range.  Has kd  butts, about 24 animal profiles, and broad head pits with 50+ yards available,  Be glad to have you come up and shoot with you!  Pm sent.
