Aurora GC and Golden GC are only open to the public on weekends. Both trap and skeet at both clubs. Not sure, but I've been told Buckley AFB has skeet and trap that is open to the public. Even non-military. I find this hard to believe, but that's what I've been told. I'm a trap shooter primarily so I'd be up for anyplace with a trap field and would love to meet some of you guys.
PS - I used to belong to the Aurora GC and I recall that thier trap fields were very often booked for special shoots, not ATA but stuff like blackpowder trap and such. I now mostly shoot at Golden GC (which isn't in Golden...it's in Watkins) and have never had to wait to get onto a field. No trapboys there. They do have voice activated machines. If you don't like the auto someone has to sit out and pull every round. Not a problem for me. I prefer a human to a machine that throws a bird everytime I close my BT100.
