Rampage on a Ghost

I know they all hate me but I got a Rampage medal on a Ghost today! That's 15 frickin' kills without dying. I know it's cheap and requires no skill, but no one can get the best of me. I always have to justify it: If you're going to monopolize the snipers, rockets, and swords; I get the Ghosts!

I am not afraid of fighting anyone while not on a Ghost, too so don't think I'm a total panzy.
