# Download census-y TIGER data
# newest files for 2010 blocks are in https://census-backup.b-cdn.net/geo/tiger/TIGER2020/TABBLOCK/
# but those turned out to have 299 duplicate blocks (exactly identical) so instead
# we used https://census-backup.b-cdn.net/geo/tiger/TIGER2010/TABBLOCK/2010/
# Includes "Island areas" blocks which aren't relevant to our project but we'll take 'em for now
# 2020 are in https://census-backup.b-cdn.net/geo/tiger/TIGER2020/TABBLOCK20/
