PHOENIX -- For the second time this week, Hidden Cash rewarded an intrepid Valley resident.
The social media-based scavenger hunt left Tuesday's prize at Chelsea Park in Mesa, near Val Vista Drive and Main Street.
A woman found the $50 stash Sunday at Tempe Town Lake.
The craze started about two weeks ago in California. Since then it has expanded across the country.
The person behind Hidden Cash in Kansas, like the anonymous person in California, said the hope was the money finder would "pay it forward."
