No, do  not keep the money if you find any. It would just be like stealing an I-Pod from Wal-Mart, and that is just wrong.Also you would probably feel guilty for the rest of your life.  Plus  if I found a wad of money I would be convinced to find who dropped it.  Also you would probably just buy a decent piece of junk with the money and just play with it once.  So really if you find money  you should either just leave it where it is or find the owner but don’t keep it.
