I'm still working on 603 in Georgia (USA too early). And, getting some help from a few of our teammates. Yay! If I see that someone else has cleaned up USA in the birth place at the beginning of a group, I just skip to the next group (or two or three). On page 2!!!!
Just in case you haven't noticed, every little bit of work helps -- we've almost reached 100,000 errors cleaned up.
