Bad news, folks. This TB seems to be missing, and not because somebody took it and forgot to log the visit yet. The whole cache it was resting in has come up missing, and there is practically no chance of getting it back. See the last log entry for the cache "I-80 Waukee Rest Area."
I feel like I'm a little bit resposible, as I was the last to have it. I apologize to the owners.
