3. For more than 20 years, Willow Walker had been taking the same path to the beach from her summer cottage. The path went through a portion of her neighbor’s yard, but that was the only way to the beach. This summer when she arrived at the cottage, she discovered that the neighbor had fenced his property and she no longer had access to the beach. If Walker is unsuccessful in negotiating with her neighbor for access to the beach, what legal action can she take?
