Note: Flickr recently went through a massive server transition, and portions of the service are still being worked on. Among the problems is that mosaic thumbnails on Collections are not visible, which means my primary page here for showing groupings by year are missing those thumbnails. The links do work—only the thumbnails are missing, so you can still navigate into a year to view those photos.
Pretty sure I was still a child the last time I rode up the SkyTower. For those of you who remember it from long ago, in 2012 they removed the additional fee, so riding up is no additional charge beyond park admission.
