Fun, but a bit challenging, puzzle. However, there is an error on the poster. I am happy that you named Mt Rainier correctly - the 500pc Seattle puzzle I have it was incorrectly referred to as Mt Hood.
On the poster for this 1000pc I Love Seattle puzzle, #34 mentioned that "On a clear day one can see Mount Rainier from as far away as Corvallis, Oregon as well as Victoria British Columbia" You should edit to simply "Mount Rainier". It is not visible from the 2 locations listed. From Victoria, you can most likely see Mount Baker, near Bellingham, Washington to the east. From Corvallis, people most likely see Mount Hood, near Portland to the north.
I love that the puzzles come with these informative posters but I believe it should be updated for future printing.
We have all of Dowdle's Seattle puzzles, and this one is by far the most colorful and playful. It's especially fun to put together after watching the episode of "Painting The Town" featuring the Emerald City!
