Oh yeah, I've been to Multnomah Falls. And it's definitely one of the best in the NW, as you can see here (this is my main site, the other one is still in it's fledgling stages, but growing fast). I'd post more, but I'm currently in the middle of updating all of my BC stuff, and I've only got about 1/3 of my pictures scanned right now.
Crooked Falls certainly looked different this weekend. They are huge and very powerful now, tons of water coming down! We got very wet trying to take some pictures. I think BeerSnob managed to snap some, hope he'll post it.
