I've been meaning to get around to this for a while now...
For all of you Pittsburgh fans out there, I posted a new thread
here with some pictures of a tour I took of the US Steel tower back in 2012 that I thought some of you may appreciate. Most of it focuses on the impressive mechanical aspects of the building, but there's some misty skyline shots, including some rare views of the old igloo being torn down (the weather was terrible, but made for some compelling images nonetheless). Hope you enjoy!
