A great tour of the history of Seattle based in the popular Pioneer Square district of downtown seattle. It is a for-profit tour through the underground sections of Seattle, explaining how it grew up from a logging town to the cultural center it is today.
The tour is a huge tourist attraction and many people simply love it. I could explain all about it, but you really ought to visit and see it for yourself. There is an interesting book that they try to sell you after the tour called "Sons of the Profits" (pun intended). Buy it. Its really is as good as they rave about... and its only a few dollars/
