When we were cleaning up at the last event, LANified! 13: The Swarm, we collected two items that were left behind.
One is a Roots Bag and the other is a fuzzy black sheet with zippers on the sides that we can't make sense of. If you are the owner or know the owner of these items please contact us to arrange getting them back in your hands.

We did not find any other items during clean up.
