I was camping, that night, after fishing that day, with 2 other friends. I awoke in the middle of the night, to a "very strange" "loud" unfamiliar sound, I was scared stiff, and scared to even move. Once I finally decided to see what was going on, I unzipped tent, and poked my head out to see/hear the most surreal sound & sight, about less than 100 yards away, above the treeline/treetops, it was a "humming/mechanical loud" dull sound, that I remember most, and what I saw, was lights, " shining down word", could not make out much from distance, tress's etc, but know it was very bright, and shinning downward, going past right above the trees tops, methodical, slow, unreal, hairs on back of neck raised. I was stiff with fear, trying to comprehend anything that I could relate to what I was hearing/seeing. I tried to wake others in tent, but to no luck, just "whatever" in response. I have mentioned it over the years, as that I truly believe I saw a UFO. the guys I fished with that trip, still tease me to this day!We were in a remote part of Colorado, & the camping spot we picked out, had no one else around. I can say, without a doubt, the sound & the lights, even though were restricted, my mind put together, that it was "circular" in shape, shining down word & bright from the distance I was from it, max 100 yards, more like 75-100 yards away. Like I have stated, the "sound" was the most unnerving part of the experience, not a "helecopter" or anything that could move that slowly, that I can imagine. It was somewhat big, size I recall in my mind trying to comprehend, was like 10-15 yards, I'm using a "football field to judge distance & size, so could be off.my ride is here, after work, thought I would riffle this off if it had any interest.Sincerely,Brett
