Are there any circumstances (in the summer months) when it is legal to light a campfire?

I envisioned a big backyard based on years of Colorado Tourism TV Ads.  There's permits and planing and impossible-to-predict weather.

If one is fortunate enough to get into a campsite, they could find themselves booked on arson for toasting a marshmallow or branded a sex offender for life for watering a tree.

Marijuana may be legal here, unfortunately it has yet to find its way into the hands of those who need it most.

Oh country road, take me home...
