wioutdoors

Just wondering if anyone knows of any good places to shoot outdoors inor around the Denver, CO, area. I live downtown, so my immediate options seem kind of limited. Are there any local parks that maintain outdoor ranges? I can always resort to shooting indoors, but I really love going out in the evening and plunking a few into a bale. I'd be more than willing to join a cluband/or pay for useif the location and hours of operation are good.

Thanks in advance for any input.
