I think it came off at the Memorial turf fields today (Mon Nov 18th) - It's lightly textured on the outside and has 'WG' stamped on the inside. Has a lot of sentimental value... I'm going to head back there tomorrow morning and look - but please shoot me a text if you've heard of anyone finding it. Thanks! - Will - 604-802-5557.
Update: Found it! Was in my car! Thanks!
