Thing about the work around on Denver is that DPD is notorious for getting things wrong. So while you may legally be able to carry so long as you aren't staying there, if DPD sees you get out of a car while OC and has a wild hair it's gonna be inconvenient at best. The other places you'll be fine, especially further away from Denver/Boulder. Remember, signs have no force of law but they can ask you to leave. OH, and depending on where you're staying in Wheat Ridge, the East border of Wheat Ridge (Sheridan) is the West border of Denver. FYI.
