Just got a call from this number, it came up listed as a wireless number from Wyoming. It's a t-mobile number, with a private listing.  I answered and you could hear what sounded like the ding noise when you put your key in the ignition. I said "hello?" they said nothing and promptly hung up.  Jerks.
