Remember these three things anytime you have to deal with a cop or LEO. Your rights do not change just because you are on public land, such as a ski area parking lot, put in, road etc.
1) I do not consent to searches.
2) Am i being charged with anything?
3) Am I free to go?
Always be polite, or you risk being charged with resisting harrassment. But knowing you rights is always a good thing. Unless they have something to charge you with then talking with them is voluntary. Therefore you should be free to go. So repeat step 2 and 3 until they realize that you are aware of your rights and will not be bullied. If they have to ask to search you then they do not have any charges and they are fishing. But if they search you without any probable cause then it is an illegal search and seizure and with a bloodsucking lawyer you can get the charges dismissed. If you consent to a search you are screwed.
I have used these steps on a few gungho fort collins cops who were bored and looking to go fishing. Once it was a tail light and once it was my brights on during the day. Both times they tried to get me to consent to a search. They will keep asking, so just keep politly reciting steps 2 and 3 as well as 1 everytime they ask to search yourself or your vehicle. Also despite Amend 64 possesion is still a federal offense. So it can be up to the Forest Circus LEO whether to charge you with possesion in CO or WA.
