As a former Co Parks Officer I can offer simple advise-Don't give an officer a reason (reasonable suspicion ) to make contact.
Everyone has a PFD at all times.
Don't stand out (you don't have to be faster than the bear, just faster than the next guy).
NO visible hard booze.
Don't be an asshole.
Don't be in a hurry to shuttle, cause if they are serious they will have Parks & CSP officers at choke points to catch folks-an average river living dirtbag can function just fine at 8.1, but is still a criminal under the law. Kind of like leaving the bar at 2AM, just dumb cause thats DUI time.
Be smart about where & when you smoke. NOTHING would piss me off more cause I did my absolute best NOT to notice that shit, but some people are just idiots.
I've been gone for a while, does CO still have a law against public consumption of booze stronger than 3.2%? It was an easy way in for me back in the day.... After that, well, you see what you see.......
Never get out of the boat
