Looks we're getting to that time of the year again, so this thread should become a little more active over the next few months. We'll have to see how the weather turns out.
In the meantime, I just ran across this very cool image of a waterfall I wanted to share with you (not my picture, just something I found on the net).
Nabegataki Falls in Oguni, Kumamoto Japan. Maybe some of you are already familiar with it?
