Yes, that tree in front of the waterfall in the first picture is really frustrating. Unfortunately there's not really much room to move for a different perspective. It's right at a very sharp curve in the road. I've actually lived here two years and driven that road many time and never knew you could see the waterfall from there. There's a scenic viewpoint up closer, but really doesn't do the waterfall justice from a photography standpoint. The first picture was using my 100mm, so maybe soon I'll head back, try moving around, and use a tripod to allow a longer exposure.
It's always fun to get different opinions. It seems almost a 50/50 split on the photos.
