How did you decide initial order for that queue?

I notice that the population of US counties varies from nearly
10,000,000 (Los Angeles County, CA) to just 60 (Loving County, TX. And
yes, that is sixty, not six hundred or sixty thousand or anything.

See http://www.census.gov/popest/datasets.html#county for the full dataset.

It might be sensible to start with the biggest counties on that list and
work your way down, so that we get the maximum percentage population
covered for the lowest possible upload time at the beginning. It looks
like about half the population lives in the largest 150 counties, which
at 6 counties/day will take less than a month.

Of course, it's probably the case that those 150 counties also have most
of the TIGER data, so it might be sensible to divide the populations of
each county by the data size and order by that figure.
