Wonder how most people do

How do you do trying to place states on a map?

I got 80% right, average distance of 51 miles, and took 528 seconds (granted, I was in a meeting while playing it).

I think the test would be better if you didn't get to use the already placed states as guides, b/c the last 1/3 of the challenge is pretty easy because most of the map is already filled in.
