What the other states have done/are doing was presented in the article to make it appear that Colorado might not be doing it right or behind the times, etc. Not to educate the public on what other states may be doing well.

Several other Western states operate combined parks and wildlife agencies, including Montana, South Dakota, Nebraska, Kansas and Texas. Washington and Oregon are also currently in the process of combining their wildlife and parks programs.
With the current economic issues we face, I appreciate that DOW funds itself and while I don't know details of surrounding states, I doubt thier DOW agencies are self funded.
