Saw a object of about 2-3 hundred ft. long, height- 100-150ft, width – 50-75ft at first thought it was a very strange flag. as i keep looking & as i got nearer i realized it was something i had never thought i would see, very alien to me, not sure after thinking about it for a while, could of been a portal of some kind? looked gold but was probably a reflective silver surface reflecting the goldish red sun shining through the clouds in the morning.When i first i saw the ufo it was hovering in the middle of some dark clouds. i would of not seen it unless i had been right where i was. after looking & coming to realize what was before me in the short time, i pulled over so i could look but, before i could it just disappeared. i know i saw something very significant. i became disturbed about it for a while & quit my job after that. was fearful for a while!
