For the most part thanks for doing this, but please check if the imported geometry is actually replacing old TIGER data rather than ways that have been updated by users since. For instance in Houston county (my area), the public domain record of the counties establishment define part of the border with Dale county as the west and north bank of the Choctawhatchee and Little Choctawhatchee rivers, which has been reverted back to the inaccurate TIGER data with this changeset. I have not looked around the rest of the state, that's just what I've noticed so far. Thanks
