I lost my keys Thursday (5/20) during 4:30~5:30 when I was around main quad. I have been looking for them everywhere in the past week but without any success.
It is a set of about 10 keys chained together, with a black bottle opener. The keys might fall off near building 200 area. If anyone found it or have seen it somewhere, please call me 650-796-7605 or send me an email. I would greatly appreciate your help.
