Ah interesting, I seen the title "run into" as "bump into" or in this context, get to where 100k people are. I don't know any US addresses far from population centers so I pumped in Area 51!
Clarity needed on the title or description!
You could replace with bump into and the comment would still apply though, no?
It says right at the top of the website:
> From the pin, a filled 5° slice in every direction. Petal length = distance to 100k people.
