Keys on black ring with green silicone cover

Found a set of keys this afternoon around 3:15pm in the parking lot behind the Bellingham Public Library on Central Ave. They’re on a black metal ring with a bright green silicone cover on one key. There are six keys in total, including a silver Honda car key, a brass house key, and a small blue USB drive clipped to the ring. One key has a yellow paw-print sticker with 'MKT' scribbled on it, so it’s easy to spot. They’re a bit scuffed but otherwise in good shape; if these belong to you, I’d love to get them back to their owner.
