I almost had a close encounter of the third kind. Have unique scar on right knee. Can't remember any enjory

While driving to the Talahassee forest in a Winnebago on the newly compleated Interstate 10, I noticed a red light in the sky to the south of us out over the Gulf of Mexico.  It started moving towards us as I was traveling at about 50 MPH.  The closer it got the lighter it got in color.  It turned white and started moving along with me about a mile away and 500 feet in altitude.  It stayed abrest of me after making a 90 degree turn.  I pointed it out to my wife and she laughed it off as a plane.  Planes dont travel that fast and make 90 degree turns I said.  I stayed visable in my side window for 10 or so miles.  Then suddenly jumped from the side window to my windshield view and hovered with a sudden stop.  Wife said Helecopter.  No! I said can't be.  I was Marine Air Wing and what it did was imposible.  When I came abrest of it it started pacing me again.  Then climed away from us and slowly turned red at a distance of 30K feet and 20 or so miles away then the light went off.
We reached the camp ground at about Midnight and driving through the woods reached a clearing.  Over the trees miles away the red light came back on.  I stopped and it raced toward us turning white it stopped over us with out a sound, it hovered. and glowed.  I started to go out and see what it was and when I ouened the door my skin crawled.  Our little girl came out of the bed screaming, crying for us to stop the noise it hurt her ears.  We heard nothing.  with that I jumped into the drivers seat and turned the Winnebago around driving out of the forest.  It started moving and I stopped looking in the large trucker mirrors. It went streight up, no sound turned red and dissappeared.
Witness indicates that the date of the sighting is approximate.  PD
