First - check with the Boy Scout camp to see if you are allowed to go there while your boys are there. Why? Because of the issues with background checks, etc. you may not have one and therefore may not be allowed to go to the camp.
Why not look into a Dude Ranch in the Pueblo area or even the Colorado Springs area??
