Had A Blast!
By A Yahoo! Contributor, 8/24/11
The most fun thing I have done in Portland!, Be prepared to get drenched not just wet, took some spare clothes so it was fine, would do it again. Not for young kids under 6, might be too scary. The guide gave us a thrill ride and lots of interesting local stuff was pointed out, places you can't see from the freeway etc. Can't wait to go back.
