In like 2003 my sister and I were driving home through a big stretch of country and we saw a fucking huge ass disc with lights around the edge jet up from the tree line and disappear into the clouds at an extreme speed. I don't think it was aliens but damn I sure will always wonder wtf that thing was.
I saw a wierd light in the sky that seemed to just hover in place for the longest time on the horizon and it was starting to freak me out, then it started moving to the side and realized it was just a plane that was headed my direction when I saw the taillight. So lame.
