all outdoor shooting has been temporary closed on state land due to fire conditions. That said, we're getting rain the next 4 days....and now there's flash floor warnings due to all the fire damage.
where are you staying, maybe I can point you in the right direction for some indoor shooting. There are a few 100 yard indoor ranges not far from Denver.
I lived in CO for a while. They didnt issue concealed permits then, don't know if that loosened up a bit. The guys in the gun shops would all start bragging about open carry but dont do it. Like here, you start walking around with a gun strapped on and you wont get very far. Really rural areas different story, you MIGHT be able to without being stopped. I lived in southern Colorado and you could just go outside the city limits and shoot. It was pretty much desert and nothing really to burn although I did belong to 2 clubs. If you are heading to a smaller city, not Denver area or Springs, a quick call to the local PD or Sheriffs office and they will be happy to point you to an area outside of town where you can shoot, provided its not a fire hazard at the moment. It's a different world out there but it was changing fast with transplants from other not so gun friendly states.
the state now has a "shall issue"...takes up to 90 days, but as long as you're not federally prohibited, you get your CCW (LTC). The only thing you need as far as gun ownership and only if you wish to conceal carry. Open carry is legal, except in the cities of Denver and Aurora. I see people open carrying a few times a week, and do so myself on occasion. People don't freak out...people don't call the cops (although they may in Boulder, but it is still legal).
There are a few stupid laws here too, most were passed right after Columbine. For example all guns that are purchased at a gun show must get a background check (both state and federal). If I meet you at a gun show, and you say that you have a gun you're selling , and a month later I meet you someplace and buy it from you, the state considers that the sale was started at a gunshow and you need to have a background check.....but if you put a gun on craigslist I can meet you in a parking lot and exchange gun for cash with just a handshake (if you want).. providing you have no reason to believe that I'm a prohibited person, and we both live in the same state.
and Denver has some kind of assault weapon ban, that I really don't understand because I've never looked into it
and just about every weekend there's a gunshow in a short drive
