Also, I lost my laptop bag this weekend. It is black with a shoulder strap, and contains an A/C adapter in the front pocket, a red book called 'The New Middle East' as well as a blue and black pencil case (which can be seen since the bag's zipper is broken), as well as a Lenovo G500 with a message on a piece of tape that reads 'broken hinge' or something to that effect.
I just went to the lost and found and provided them with this description, but unfortunately they did not have it. However, they said that Saturday evening is relatively recent, so I will check again with them later this week.
The description above is detailed, but the staff at the lost and found asked me if I had a photo, or if there was any ID within the bag. Please Forum PM me this information.
EDIT: I'm not at all blaming Peter, but I would just like to make a friendly PSA to remind people to watch their valuable belongings periodically if you leave them in a room, and note that doing so is at your own risk. That being said, all tournament attendees should make a collective effort to keep an eye out for suspicious behaviour/external people. To be honest, I'm not surprised that buzzers are never stolen when left in dark, closed, yet unlocked rooms. I suppose a possible thief/the general public doesn't realize how expensive they are.
Yes, this tournament, like many other quizbowl tournaments, took place in a very quiet basement of a building at the edge of a campus that felt like a ghost town on the weekend of the summer exam period, but TDs are often unable to lock and unlock their rooms.
Theft is still common at university campuses, especially if the entire tournament goes out for lunch together. Of course, you shouldn't force anybody to stay back, but kindly ask around if anybody will be staying in the rooms because they packed a lunch/are ordering in/etc.
For the specific case a laptop, I would recommend buying a Kensington keyed lock (I can find them for $10 or less on Kijiji), but even this is not bulletproof and you should still periodically check on your laptop between every couple of rounds if it is in a non-game room.
