Tired of city life, Sam walked up into the mountains, where he found an old shack. Inside the shack he found a note that read: Welcome. I have been sheltered by strangers when I needed help and want to do the same. You have my permission to stay here for free. Sam lived in the shack openly and continuously for 30 years. Then, one day a man named Barney knocked on the door of the shack and explained that he owned the property, but he had decided to sell it so Sam needed to leave. Sam refused, claiming that the shack was his now. Who owns the shack?

	a.	Sam, because he satisfied all of the criteria for adverse possession.
	b.	Barney, because Sam did not satisfy all of the criteria for adverse possession.
	c.	Sam, because the Shack was abandoned property.
	d.	Barney, because the facts establish his life estate.
