Neon white craft in the southern Sierra Mountain range.Let me start this by saying that I have had a lifelong interest in the ufo subject. I am 29 years old and was born and raised in Bakersfield, CA. Despite this, I have never seen anything that I could not explain in the sky. I believe that changed on Sunday, November 15, 2015.I was driving home on Rancheria rd. which lies about 10-15 miles east of Bakersfield. Rancheria runs north and south and will take you from east Bakersfield all the way up to the Alta Sierra area.This particular day was a very rare and stormy day for this area. There was rain, snow and tiny hail coming down all day. I am a 4x4 enthusiast and was going up a trail called "Freeway Ridge" with a small group of friends. This trail starts at hwy. 178 and ends at Evans flat campground and traverses through the southern sierras. After a long and muddy day of 4 wheeling we finally reached the end of the trail. Rancheria road is the quickest way back to Bakersfield. Rancheria is winding road that is very dangerous, especially when wet. We were going south at an average of about 15 mph. It is 25 miles back to Bakersfield as the crow flies but it takes at least an hour to drive on any given day. Visibility was very low because of rain, fog, and mud covered vehicles. This day it took us about 1.5 hrs to travel this 25 mile road. Now on to my sighting. About 15 miles south of Evan's Flat campground, I see a light coming down towards the mountain. It looked like a small plane at first and was approx. 4-500 yards to my left. I am a golfer, so I feel like I am a good judge of yardage. I almost panicked at first because it looked like this small plane was going to crash into the mountain to my left. It was very low to the tree line. As I focused in on this light (difficult with mud covered windows/windshield) I could see that it was not a plane of any kind. I got a clear look at it for about 3-4 seconds. It was 2 bright neon white round balls with a thin neon white line connecting them. It did not produce any halo of light behind it. It was traveling on a horizontal plane and coming down diagonally towards the ground. Its flight is why I originally thought a plane was going to crash. After the 3-4 seconds, I could see it fly behind some trees, and then it disappeared. Let me also mention that this was 15 min. after sunset with complete cloud cover and rain. It was basically dark outside.While this whole experience was seemingly mundane it was also very spectacular to me. I couldn't begin to come up with a logical explanation of what this thing could have been. It gave me the chills and made the hair on my body stand on end. I apologize for the wordy post but I wanted to be as thorough as possible. Strange things are definitely out there. Thank you!
