'Hidden Cash' heads to Kenneth Hahn Park

BALDWIN HILLS, LOS ANGELES (KABC) -- The man behind the @HiddenCash craze was back at it Friday night, but the Twitter-based treasure hunt didn't go off as smoothly as planned.

Hundreds flocked to Kenneth Hahn State Recreation Park in Los Angeles, following the clues tweeted by @HiddenCash. Some found $100 and $50 bills.

This evening's hunt, however, held something extra. Letters circled on five envelopes spelled out a word that hinted at tomorrow's search location in the Inland Empire.

Groups teamed up to work out the hidden message, but at about 8:15 p.m. the park closed. Authorities notified participants that they would need to leave the park or be cited.

@HiddenCash apologized via Twitter, saying: "I'm sorry people. It took me longer to prepare and get there (traffic) and do the drop than I anticipated. We have three more this weekend."

This is his second "Hidden Cash" visit to the area. He also drew big crowds when he was here last month.
