Other than reciprocity, what else do I need to check or know regarding going on a road trip across several other states? Mostly worried about the west coast with weird rules I don't know.

Licensed in Colorado.Firearm will be kept holstered in my backpack when not carried, don't want to have it on during 5000 miles of driving. Mostly bringing for numerous nights of camping and sleeping in the car in the backcountry.Edit: I suppose it will help to list the states we will be passing through and staying in: Colorado to Utah, Idaho, Oregon, California, Oregon again, Washington, Montana, Wyoming. via /r/CCW https://ift.tt/2VfLLuC
