McDonald’s McRib returning to Washington, but it may be the last time you can ever get one

One of McDonald’s most popular sandwiches is coming back, but this might be your last chance to ever eat it again.

McDonald’s announced the return of the McRib, but it came with some bad news: this will be the McRib’s farewell tour.

The McRib will be coming back to participating stores across the country on Oct. 31, according to a news release.

The sandwich is made with a boneless pork patty, McRib BBQ sauce, pickles and onions on a homestyle bun. It’s 520 calories.

A website also has been created for those searching for the sandwich, the McRib Locator.

Users can report where they have spotted the McRib, search the nationwide map to find one, or search near their location for the nearest McRib.
