puzzles are white hot now!

This puzzle is cool, as you can pretty much tell where any piece goes by looking at the piece. I laid out a grid om the table so I know here each piece sort of goes, but there is a lot of pure black so those pieces are very difficult to place. Still working on it a few minutes every hour. Its best when all 4 of us are around it chatting it up and asking for eyes on critical pieces. 3 of the cars are very close in color so that makes it even more difficult.
