Dear Greg,
        I cannot tell you HOW EXCITING THIS IS! My entire
Collecting and dealing history I have maintained that the
Most killer meteorite would come from EARTH - knocked off,
Time in space, and then fallen back to earth.
        THAT'S WHAT YOU GOT, BABY!
        Too - Absolutely TOO cool!
        Yum, Yum, Mikey must have... When do we get a shot at
This stuff????
        Howsabout offering it to us list people FIRST??? Hu, hu,
Will ya, hu? Pleassssssse.
        Michael
