"Where Was I?" Contest #1 - Fiery Globe

Second day of this week-long contest to see if you can guess where I was when this series of photos was taken. Too hard so far? Hint: You don't have to be from Portland to know of this place. In fact, if you live in the U.S., you're sure to have heard of it--it's that well known.

Leave a guess in the comments! Or, if you're stumped, hold out for tomorrow's hint.
