The billboard is located directly adjacent to the northbound lanes of Interstate 5 in Napavine, Washington, around 8 miles (13 km) south of Chehalis, in Lewis County.

The two-sided billboard, which depicts a large painting of Uncle Sam on both sides, is located beside the northbound lanes of Interstate 5 (I-5), near Exit 72, just outside of Chehalis.

Alfred Hamilton began posting messages after I-5 was constructed across his turkey farm in the early 1960s to promote his "archconservative views in big block letters" .

[1] During the 1970s, the billboard advertised Hamilton's cattle business and in 1977, the state sued unsuccessfully for removal, claiming the landmark violated anti-billboard laws at the time.

[2] The New York Times described Hamilton as a "cranky crusader" who "loved a fight" and a "stubborn man, a turkey farmer with a big belly full of opinions".

[1] According to the paper, "Mr. Hamilton minced no words in attacking virtually everything and everyone that irritated him: gun control, the government and gays, Russians and radicals, Kissinger and Kerry.

[3] Messages that have appeared on the sign include: The billboard has elicited considerable controversy over the years and several other attempts have been made by various individuals and groups to have it legally removed.

'"[1] A local resident, Kyle Wheeler, in response and opposition to the billboard as well as to the rise in hate speech and crimes towards the LGBTQ population, erected a sign in the fall of 2020 that stated, "Lewis County Welcomes Everyone".

The sanctuary was created in honor of a deceased friend, Kali, and eventually grew to include birdhouses for swallows, decorated in colors associated with the gay pride movement.
