(AP Photo/Sergio Loza) If you don't live in California and you were a bit bummed to be missing out on the "Hidden Cash" craze, look on the bright side: It could hit your city next. The @HiddenCash founder tweeted yesterday that it was "our biggest day ever," with cash-stuffed envelopes hidden around New York, Houston, and Mexico City, the Los Angeles Times reports. One man who found an envelope in NYC generously gave it to a little girl who was also searching Central Park for the money, noting that he gave her "a little smile." Real estate investor Jason Buzi recently revealed himself to be behind the pay-it-forward phenomenon. (More HiddenCash stories.) Report an error
