I'm using delivery apps to travel across the country and was looking for a place to camp near Grand Junction so I could work there for a few days. I found the Zinger Farm. The site itself is nothing too special; just an open field surrounded by neighboring farms. But it has gorgeous views of the surrounding mesas, including the nearby Grand Mesa, and easy access to town and to the Colorado National Monument. No bathrooms, but cell reception is great and the folks that own it are very friendly.
