Red/Orange light over the Grayland/South Beach area of Grays Harbor County, Washington.Approximately 10:00 pm in Grayland, WA. Traveling south from Westport along the coastline, I saw a bright Reddish/Orange light in the sky approximately 100 to 150 feet above my vehicle. It was moving at about the same speed that I was traveling and in the same direction. It moved west toward the beach from Highway 101 and back toward me several times as I made my way South for nearly 3 miles. I and the vehicle behind me pulled to the side of the highway at our first opportunity. The “Light” stopped for a brief moment (approximately 2 to 3 minutes) and stayed at the same altitude and distance from my location. It then slowly began to move south again gradually gaining speed. I followed it until it seemed to decrease in size until it disappeared and was gone. There were 5 of us that seen it.
