No, but hopefully we'll get the chance this summer....seemed like every time we went to shoot waterfalls, last summer, it was trying to rain and we didn't want to take the chance on getting the gear wet.
Have you taken the trail up above Wahkeena Falls? We went as far as Fairy Falls. I didn't get any good pictures because of the extreme contrast on that sunny day. I'm hoping to be able to go back some day.
