Unknown Caterpillar - Any ideas?

Hey everyone. It's the weekend for Jennifer - yay! I've been looking, without luck, for a while now for the identification of this caterpillar. Steve and I found this gal wandering around the work lunchroom, moved her outside and hurriedly took a photo before heading back for our afternoon shifts. I wish now we had some better photos. Anyone have any identification ideas? I am pretty sure this is a moth caterpillar, but have no idea what type.
