Mackinac55 County, MI. June 1988. Weather conditions: clear, calm, twilight(dusk).Resided, hunted and fished in the exact area for 20 years(know the spot well (cut firewood and picked berries at the exact spot(I spent 9 years in the USAF as a aircraft mechanic worked many night outside sunset to sunrise and never guestioned any thing I saw.. We were riding on a two track in the deep woods looking for wildlife and talking like usual. The woods in this area are old growth forest.The 2 track we were on is like a tunnel of trees for about half mile in length. From the air Im sure you cannot see the road. I was driving slow around 3 to 5 mph.(looking for wildlife and enjoying time with my sister). We were most of the way through the tunnel of trees. I knew exackly where I was. There is a slite gradual up grade for a little bit and then you see the exit from the tunnel of trees.Up to that point the exit is not visible.( I think we surprised our UFO). Anyway as we crested the slight grade I was looking towards and talking to my sister.She said there is a truck coming( with one headlight not bright but soft white light-at this instance things faded fast, quickly. The first thing I remember- we were hunched over facing each other blinking at each other like we were just waking-up.We looked out the windshield and going across the glass( within feet-not yards), red lights (not bright) moved from front to back. The red lights were 1-2 feet long 5-6 inches wide covering the windshield, not rotating just going front to back.The wierd thing was is the craft looked translusant.Within seconds my sister starts freekingout( losing it- yelling "Oh my #&&% what was that, lets get out of here before it come after us". My reaction was different. First I told my sister to calm down. Then I told her I was getting out of the truck to look.She thought I was nuts.Once in a life time chance I thought to maybe see something out of this world.I got out of the truck guick enough I thought, looked all around, up down, in and out,saw nothing, no leaves moving just feet above us. What was the object?One other thing,there is a highline at the exit of the tree tunnel.
