If you live in the San Francisco area and want to make some extra cash, you should go on twitter creat an account and follow @HiddenCash.
The unidentified user is having a little fun by hiding money all over the city and then takes it to twitter with pictures and riddles for the location of the cash.
I hope this will set a trend for other millionaires to get inspired and play hide and seek with their own money.
Be sure to follow @HiddenCash because he might come to a city near you.
