In October 2002, I was driving east on Interestate 40 (close to mile marker 100), when I saw a greenish "comet-like" shape movng very close to the ground and apparently very fast. It was moving in a west to east direction and was to the north of me.About a month later, I saw the same thing, but on Santa Fe Blvd. in Grants, NM, this time traveling north to south.((NUFORC Note: Date is approximate.
