About 10 days into this megaproject, and the boy is on page 85 (which included doing the same 4 pages 7 times). All 7 legs are now on, and he is working on piecing the big afterburners section together. He should get that on this evening, but he will be home from school late tonight.
Still, progress is being made. We're getting rid of a lot of the bigger pieces, but still have thousands of tiny pieces left.
