Welcome to OCDO! First off, OC is legal both statutorily and constitutionally in Colorado. Unfortunately, OC is not legal in the City & County of Denver per the Meyers decision (check out www.rmgo.org for more info) outside of your home or place of business. If you OC in public in Denver, expect to be arrested. I've OCed outside Denver almost everyday for about 9 months and I cannot recall ever seeing another OCer. I've run into a few LEOs while OCing without an issue. Most people simply don't know it's legal.
