Some individuals have quite an infatuation with the delicacy.

Take Ryan Dixon, for instance. He is from Burbank, CA, and once drove 10 hours to Medford, OR, to get his hands on a McRib, reports FOX News.

The McRib sandwich was first introduced in 1982, reports the Washington Post.

It is made of a pork patty, onions, pickle slices, and savory barbecue sauce.

The McRib will be released en masse across McDonalds' nationwide chains until Nov. 14.
