The more Denver grows, the harder it is to find a place to bust up a few clays, sight in your rifle prior to hunting season, or just make a lot of noise with your gun collection. Legally, anyway. Fortunately, there is the four-decade-old shooting center in Cherry Creek State Park. There, within sight of Denver's tallest buildings and its south suburbs' fast-growing developments, city-dwelling gun enthusiasts can discharge almost anything they can buy -- pistols, rifles (25-, 50- and 100-yard ranges) and shotguns, including trap, skeet and sporting clays. The range is open Thursday through Sunday; ten bucks will get you a gun to use, and another ten will cover the fee.
