All Counties of the United States by Proximity - Disappear Version
When you name a county (or equivalent) of a U.S. State, all counties within 100km of its center will also be filled in. Once a county is guessed, it will disappear from the map!
Caution: the map is large in size, and with 3k+ answers, the page WILL BE SLOW
Distance here is the centre-centre distance using the latitude/longitude geographical centres provided by the U.S. Census Bureau. (This means for a big county, its borders may not get activated)
