Do you know if anyone has ever tried to walk, drive, or fly directly toward the lights? Day or night? Has anyone photographed the lights and then photographed the same spot during the daytime?

I've driven that highway several times, and I've ridden along on the Amtrak which runs along that road. Further to the West the rail track and the highway are closer to Mexico and I could see fires burning in Mexico and also the lights from Mexican towns. If I wanted to, I could rent an airplane and fly from Highway 90 directly to the location of the lights during the day to see the source of them. Has anyone done this with the Marfa lights?

Has anyone been out in the desert with a car, South of your viewing position, aiming the car back toward Highway 90, flashing their lights as a test to see how far away they can be seen from the highway?

I see on my map a small town of Peridiz, South of Marfa, to the East of the highway to Presidio. Has anyone taken a car to Peridiz and flashed the lights back toward Highway 90 to give a distance marker to viewers on Highway 90?

Is there a road from Peridiz to the East to Highway 118? A road from Peridiz to Highway 118 would pass East to West about 18 miles South of your viewing position.

Where I live in the Western desert I can see single street lights (used as night-lights on ranches) at least 25 miles away.

Is there a private airport in the desert between Peridiz and Highway 118? Some of the South Texas ranchers have their own airplanes.

Campfire lights could have been seen in the desert in the 1880s.
