I've posted something similar to this about the top 10 counties in terms of size and landmass. I'm still mesmerized that the biggest city which is NYC has some of the smallest counties. Los Angeles is the second largest city but has the largest county. California has most of the largest counties with Arizona and Texas coming in next, and Florida and New York rounding out the ten. In terms of landmass, Nevada and Arizona have the largest counties with California coming in second, and Wyoming and Oregon rounding out the ten. This is sort of a repeat but this stuff is fascinating to me. (Source: Wikipedia)
