Marc noticed this onion sign at Safeway, which is a grocery chain. So are were these vegetables imported? Are they from the USA? Did Marc secretly pass through a wormhole and end up in an alternate-universe Safeway where his state has seceded from the United States, or just this Safeway? Maybe all Safeways have seceded, and this is how they’re letting us know.
Or it could be that the sign was put up in error, and the onions came from Peru.
Update: To clarify, Marc lives in Delaware, not in Canada.
