Cash drop creates Twitter frenzy
Someone is dropping envelopes full of cash across San Francisco, causing a social media frenzy.
The mysterious person with the Twitter handle @HiddenCash has been hiding money throughout the city since Friday, leading scores on a scavenger hunt.
His Twitter following has exploded from a few hundred on Friday to more than 75,000 and counting by Tuesday.
Hidden Cash's creator says his giveaways are a "social experiment for good". He claims to make his money from San Francisco's property market and hopes that winners also pay it forward.
Adam Wenger, a 27-year-old web producer, said he won 200 dollars (£118) finding two envelopes in the city's South of Market District. He bought pizza for his co-workers and will pay a 100 dollar (£59) parking ticket with his cash.
