Honestly, if I found a backpack containing over $3000 in cash, I'm pretty sure I'd pay off some bills or get a boat load of shoes. But this *homeless* guy in Arizona is a more righteous person than I. (Okay, most are more righteous than I.)
After finding a backpack on the train line, Dave Tally discovered the cash, a laptop, and a flash drive containing the backpack's owner's resume. He used the information on the resume to track down the owner and return the contents of the backpack, including the cash.
You can reward and help Dave Tally for his integrity and humanity here.
