I've not had the "pleasure" of OCing in C City yet, but being that it's not Denver County (but really close!), you should be fine. I would definitely review the ordinances and statutes for Adams Co., and Commerce City before venturing out n'about. Be aware of county and city borders, posted areas, etc. It does take a reasonable amount of research and it can be rather draining, but it's achievable and rewarding!
I've been OCing in Douglas Co for a couple of months now, but now that my CCW is about to arrive, I've been kinda laying off. Usually with me, the bottom falls out right before something positive happens. I don't want any hassles with the Sheriffs Dept or locals before my permit resides in my wallet.
Overall, most of the events that you'll read about in the Colorado forum are very positive. Keep an open mind, you're eyes peeled, and be safe.
