[Talk-us] TIGER road expansion code

[Dale Puch]

A better question is how will we determine an error rate?

Personally 1 in 10,000 would be worth running the script for me.  But I
would be much happier with 1 in 1,000,000 and a higher skip rate for the
odd cases.  Keeping in mind 1 in 1,000,000 is probably  0.5 to 1 error per
state on average.  That would be ridiculously good.
