You thought it was strange for us to try to run a race in every North Carolina county? Here's a guy with a county-collecting blog dedicated to his efforts to visit every county of every state in the country! This post documents his visit in February to Stokes County, the last of North Carolina's 100 counties he visited. Stokes County was the 2,898th county he had visited, out of 3,141 counties (or county equivalents) nationwide.
I don't think we'll be trying to run in all the counties in the country, though.
