Alaska, North Dakota, & District of Columbia are verified
Alaska, North Dakota, and the District of Columbia have all been verified by a human.
Alaska was the hard one. Something like 90% of the farmers markets and a lot of the local events have no website at all — they run on a Facebook page, and contact information is thin to nonexistent. If there's no email and no phone number, your options are to send a Facebook message and wait, or live close enough to drive over and talk to somebody. In Alaska, driving over is often not a thing you can do. Kotzebue is off the road system. Ketchikan and Petersburg are air-or-ferry only.
The deeper problem is that a Facebook post is a snapshot, not a listing. It tells you an event happened. It does not tell you the event is still happening. The Kenai chamber's holiday bazaar post was written in November 2025 and carries 2025 dates. A Tanana Chiefs bazaar announcement was three years old and still the newest thing available. One Ninilchik listing had a date that a third-party site had worked out from the previous year's Saturday cadence, which is a guess wearing a fact's clothing. I had to decide, event by event, whether an old post meant a dormant event or just a page nobody updates. Sometimes the only way to know is to ask a person.
North Dakota was cleaner on paper, which is its own trap. The information exists, but a lot of it arrives pre-digested — search summaries built on top of Facebook posts, citing links that don't survive. One source handed me the Adams County Fair with a century of Colorado history in the first half and a Nebraska fairgrounds address in the second, merged into a single confident block of text. Adams County exists in both states. So does Crete. So does Bristol, in two other states I've done. Every one of those is a wrong row waiting to happen, and the only defense is checking the address against the county rather than trusting the name.
The other North Dakota wrinkle is operators running multiple events under one banner. The Bismarck and Minot Christmas shows are the same outfit. The Fargo market that turned up as one Saturday listing had a second market day buried on the site. One name does not reliably mean one event.
The District of Columbia went quickly, but not for the reason you'd expect. The challenge there is that DC events don't call themselves DC events. They go by neighborhood. H Street. Petworth. Dupont Circle. Nothing in the name says Washington DC, and a vendor searching the obvious terms turns up almost nothing. Getting the District right was less about confirming facts than about knowing the map well enough to recognize a listing as belonging to the District in the first place.
Progress is being made. Slow, but steady.
