Take the Money and Run?

Ok, lets say you are walking through the parking lot of a bank and you see a bag sitting by the trash cans close to the ally. Inside the bag you find it is filled with cash. Lets say enough cash to pay for your 4 years at Columbia. Knowing that there is no one around and no cameras to see, do you take the bag without a second thought, take it into the bank and report it or give it to the homeless family walked by to get to the bank?
