Football in South America bears no resemblance to U.S. football, but the Chilean Avocado Importers Association has become a big fan of the American game.

The association kicked off a season long-promotion Labor Day weekend by inviting American football fans to submit photos of their pre-and-post-game tailgate parties. There will be two weekly winners of $50 gift cards, according to a news release.

“Avocados have always been a key player in consumers’ favorite tailgating dishes,” Maggie Bezart, association marketing director, said in the release. “Our Tailgater of the Week Contest is the perfect opportunity to engage fans and spread that football fervor from the parking lots to the virtual world.”

Tailgate party photos are to be submitted via the association’s Chilean Avocado Lover’s Club Facebook page. Facebook users vote on the photos and the association will announce winners on Fridays, according to the release.

“The interactive voting process will allow everyone to participate in the fun and build up our online community,” Bezart said.

The contest continues through Dec. 23.
