Why It's Awesome: Donald Dettloff's surfboard fence started in 1990 when he heard a hurricane was approaching and wired his boards together to keep them from blowing away. Instead of taking it down when the weather had cleared, he decided to keep it up and continue adding boards. Now he has 647 different surfboards, displayed around his property in Haiku, Maui, which earned him a Guinness World Record for the largest collection of surfboards.

Accessibility: The fence is on Kaupakalua Road and can't be missed.
