There was a recent Grand Canyon shot here which made look back at my old Grand Canyon pano.
Alas, it was nowhere to be found, and I also recently deleted some really old backups so no hope there. I could only find a small jpeg on my site. Fortunately my original files are still available so I went through creating another pano, some 7+ years later now. Different software (initially went through PTGui this time instead of Photoshop). Technically I think it's clearly better but the mood was just not the same; I further played with individual colors and I think it's significantly closer now.
What do you think?
PS. As a side note PTGui was able to use more of the original shots, even after some subsequent warping in Photoshop
