I was standing outside my trailer smoking a cigarette. as always, i was star gazing. looking for shooting stars and satellites. i cant recall if it made a hiss or a static sound, then i noticed a chevron shape moving in the sky. my first thought was that it was a flock of birds flying south for the winter. Then i noticed that there wasn't any wings flapping or a break in the formation. then i thought, "What the hell is that?" i couldn't make out much detail of the object, the chevron shape i saw was the leading edge of the craft reflecting light. it was at about 3,000 ft altitude moving steadily from the north east, heading south west. i followed it by the way it blocked out the stars. the size was the most impressive. as i followed it it went directly over town, that's when i noticed that the back of the craft was rectangular. i knew then it wasn't ours. or anything i know of in our military's inventory.and the size was scary, something that big moving so quietly and fast. it flew over a baseball field here, i believe it couldn't have landed in the field it was so big. it took a moment or two to realize what i just saw. i felt a little scared, awed,confused, mostly excited. when i couldn't see that object or any other in the area, i went back inside and told my girlfriend what i just saw. i followed the object from first sight to where i had to lean around the front of the trailer to follow it. when it was over town that's when i noticed the rectangular shape and the width of it. i don't recall if i looked away, or if it just disappeared?? after i lost sight of it i looked at my cellphone and noted the time and date.
