The 20th Fried Onion Burger Festival will be held in El Reno, Oklahoma, this weekend. It is always held the first Saturday in May. Last year, it featured an 850 pounder billed as the world's largest onion burger. El Reno is also located right on the world famous Route 66.
They have a great looking poster for the event with the words "Get Ready to Start Eatin'", but, unfortunately no Route 66 sign on it.

Onion burgers have been cooked in El Reno since the early 1900s. Ross Davis owned and operated the Hamburger Inn on Route 66. He began making onion burgers in the 1920s as onions were cheap and meat expensive.
