I just got a call as well and I'm from Indiana but haven't lived there for some time.  Ewwww the mystery unfolds.  Clearly this call means nothing.  No one has said anything harmful came from it.  Often times people call me who I DO know and I don't answer the phone because I just don't want to.  Treat this call that way and carry on with your silly lives.  I know, I'm silly too for writing this but I wanted to make sure it wasn't something to do with my job.  I have actually never written on any sort of post on the internet.  Somehow the idiocy of everyone writing the anticlimactic, "I got a call from this number too" was killing me and I couldn't resist.  Thanks for the laugh Indiana!   I'm still so glad I left you!
