Like cicadas or Fleetwood Mac reunion tours, the McRib only comes around once or twice in a generation. Starting today, and for the next six weeks, every McDonald's location in the US will carry the mythical manwich. Hallelujah.
The last time we had a McRibbing of this scale was all the way back in 1994. Since then, the pork(ish) patty has broken cover only occasionally, and at limited locations. Devotees were forced to turn to makeshift solutions like the McRib Locator to track them down. No longer.
