crs98: I always liked this puzzle and it pains me a bit to archive it, but I think it's time to do so.
I did confirm that the sculptures where my nano cache was hidden have been removed. I have no idea why, though construction all around the area provides a hint that they may have been removed as part of something that will happen soon. That area certainly isn't under construction at the moment.
As always, I explain how to solve my puzzles in my archive note. In this case, each of the locations in the list was a bus stop. If you went to the bus stop (in person or virtually using Google or Bing street maps), then you would note which bus route ran through that spot and it would reveal the coords.
For many years the bus routes in the Seattle Metro area were fairly stable, but with the addition of light rail and then instant collapse of some routes because of the covid19 pandemic, this has been less true over the past few years. So the idea of moving the hide to a nearby location and updating the puzzle just didn't seem that appealing as routes aren't as stable as they used to be and may change again over the next few years.
Perhaps by archiving this hide I'll open up some new space for a new enterprising and fun hide in the new transit center as it opens in 2024. Thanks to all those who found the cache in the past and I hope you enjoyed the puzzle and cache!
