Kenny is 100% correct. That's just the way the law works. It has to be specifically prohibited. There is currently no state law in Colorado that prohibits open carry in general. There are a few laws in regards to carrying in places like airports, court houses, etc. But not in general public. Anyway, in all honesty, for the problems you're bound to encounter, why bother. Just get the permit, and carry concealed whenever that's possible. Karl.
