medical bills, completeing my bucket lis

My name is Stephanie, the cute guy with me is my 10 yr old son Edwin.
  I am a single Mom.
  Like most people I have put off doing so many things with
  him because i thought i had time.
  I don't.
  I was given the news this week that I have an incurable and unoperable form of Cancer and the metastesis have already almost fully involved my liver.
  I don't want his last months with me spent waiting for me to die.
  I want the money to take a road trip vacation of a life time with him.
  I want to go see the Smithsonian, then head up to Niagra, then cut cross the upper US throu the badlands and see Mt Rushmore and Crazy horse.
  Then I would like to see the Oregon coastline and travel south to the redwood forest.
  One quick day trip into San Franciso to see the wharf.
  Next would be visiting the noth and south rim of the grand canyon thn a short trip down into Mexico to see the ruins at Panleque.
  For as short a time as I have left I want to accomplish as much of this road trip as I can.
  I have no savings but made my way without government assistance.
  Please help me give my son enough memories, to last him his life, of fun things he got to do with his mother.
