According to a log on my Preston Pennyfarthing cache, this trackable was picked up by "the Cartwrights" in February 2011
And I can confirm after a maintenance visit to the cache today that the bug is definitely not in there any more
Unfortunately "the Cartwrights" have never logged their visit to the cache online, or logged the bug retrieval, so I'm marking the travel bug as Missing so it doesn't show in the inventory for this cache any more
I hope the trackable comes back into circulation soon!
