Gino, I sent the photo of your metal object to the Engineer who designed the cargobay of the Space Shuttle. He has forwarded to photo to NASA and would be interested in knowing the longitude and latitude of the place where it was found.
Ok guys, I tried my best, I look in www. topozone. found the closest ranch that was listed, and I come up with Lat. 27.824 N, Lon 99.536 W. Hope this helps. The ranch listed with these cordinates is within 1-2 miles from where I found the Metal object. Keep looking down guys, you never know what U may find.
