Driving me bonkers. Sounds so familiar but I can't place it. Three days I think, now, and nobody has guessed right yet. So, this guy is hiding cash and giving it away, and he has branched out to social media as a way of giving money away. On twitter he is @IHidTheCash ( https://twitter.com/IHidTheCash ) Clues for this sound so far are: 1. Can be found in a gym 2. Can be carried in a car 3. Closest guess yet is of a plastic water bottle being squeezed You can win his cash if you guess right. He's in the DC / Baltimore area but online anyone can win.
