Yesterday (12/18), I believe I left my 32 oz. Nalgene water bottle in either Sondheim or the Math/Psych building. If SOND, I likely left it in the 5th floor women's restroom. It has a couple of stickers on it including an elephant, YETI, and "Be happy" stickers. It has a black cap and clear body.
If found, please email email@example.com. Thanks!
