A big thanks to Quizzer6794 for teaching me how to avoid horizontal gaps between pieces, eg see his US State Picture Puzzle Game #3... does anyone know how to remove vertical lines too?!
Great quiz, but I was a bit confused because there were 3 wide bands at the end while it told me I had 25/26. It turned out that Honolulu, the furthest left band but invisible before you chose it, was the final one.
this wasn't deliberate but when I realized this extra-difficulty I thought it'd be a "trick answer" (I wouldn't know how to fix it anyway) - thanks for your comment!
