Found this spot at about 7PM on a Friday night near the Breckenridge end of the Boreas Pass Trail (39.451441,-106.014294). The spot does have a fire ring but was unable to use it as a fire ban was in place at the time. Could hear some occasional traffic noise as cars were leaving the trail. Temperature got down to 16 degrees that night. Altitude is about 10,600 feet at this site.

This this is a long Winding Road up the mountain that has many nice places to pull over and Camp right off the road. Some are a bit further back than others. Most are accessible to any vehicle. Further on up the mountain you will find the remanence of an old train stop, cabin, train car… It's all free but there's been a fire ban all summer.
