I have OC'd for the past 2 years in CO, UT, NV, AZ, NM, & WY. I travel including overnight park in truck stops, Walmarts, and campgrounds a lot and many times well "off the grid" to be able to request help from anyone. I hike in National Parks and National Forests and in my 3 years of hiking have hiked within 100 meters of 3 different bears.
I was using the rest-area in NM when a LEO came up beside me in the other urinal. Just as we were leaving the restroom he asked "what are your carrying?" and we had a pleasant conversation about what we both carry on a daily basis.
I have had only a single citizen say anything to me about it but only in passing. Only a single business in CO has ever asked me to "leave the gun in the car" in which I replied "this customer leaves with it" and I did without any further discussion.
The two hardest people to convince about carrying at all was my wife and my mother, both of which stopped resisting after the Aurora, CO theater shooting.
I now have a CO CCW just in time to be able to put a jacket on this winter. It is not easy OC'ing in the winter so I finally filed for CCW specifically for the winters.
