Large sphere witnessed at music festival.One night myself and a couple friends were off-roading in the foothills behind Millpond in Bishop, Ca. We stopped at one point to look down into the valley to look at the lights coming from the music festival that happens every year there. We noticed a light coming from farther back into the hills and all noticed how the light neither changed position, nor intensity as it came towards us. It was distant enough that we could not make out any detail as to what it was or its size, but just upon casual observation, it was obvious it was not a car or anyone carrying a light. I jokingly flashed an SOS at it a few times. Our friend who was driving us around in his truck said he had to go, so he could take his mom to work. So we jumped into his pickup, a Nissan extra-cab, and drove back into town.I had thought nothing of the incident until my Mom had asked me a number of days later if I had seen the UFO article in the Register newspaper. It described a ball of light some 100-200 feet in diameter, and how it had passed over the Millpond area and the sighting of it by hundreds of people, there was also a contact number in the article (at the end IIRC) for anyone that had anything to say about it, I don't believe the number was a local one. I believe it is still on microfilm at the local paper.((NUFORC Note: Witness indicates that the date of the incident is approximate. PD))
