Trying to Write Haiku

Many of my contemporary haiku poets like to create what is known as an "aha" moment for their readers. That is, they want you to guess a little at their meaning. And while I've read some of these haiku and enjoyed them, they're not my cup of tea.

I'm more interested in what I like to call an "ah" moment. I don't want to surprise the reader or make them think. After all, it's just a 3 line poem. I want to give readers a snapshot... a picture if you will of a place and let their imaginations take over from there. For instance, I've recently written this haiku:

Hot afternoon --
a hippo slowly
submerges

There's nothing "aha" about this little poem. No. It's just there for you to see. When I read this I imagine a scene. I can see this great beast go underwater and it gives me pleasure. And why is it going underwater? Because it's hot out! Simple and Zen like.
