www.handgunlaw.us states that Colorado signs carry THE FORCE OF LAW. Of course, they do the best they can on the site and there can and will be transitionary periods before laws can be updated. That's not counting the fact that the site isn't a legal site. Someone would have to research the laws themselves. I use the site for a 'roughdraft' before taking a trip with the family to know if I "must notify an Officer", if I am "allowed to CCW within said state", etc. This doesn't mean that I am protected in any way.
