I used the raw path data to see how long one of the borders is before finding the proportion to give how many miles the 8 pixel tolerance is. However this is not the actual length because of scaling. Now I adjusted for the scaling, and it's really about 27 miles, so I changed the instructions to be more accurate.
You should make a randomized version!
