Another place to watch out for is shortly after the ride begins... you go up one belt and round the outside of the mountain. You then wait (usually a few logs in front of you) for another belt. The big drop is off to your right and there can be a tremendous whoosh of water come up from below. I think this is mechanical and not from the log hitting bottom, because it doesn't happen all of the time.
If it's cool out well grab jackets or ponchos on this ride. If the weather is warm it's no big deal... you don't get soaked like Kali.
I'd prepare with something. If you get stopped by the waterfall near the end you can get drenched after a minute or so.
My best tip is to not settle back in your seat right after boarding. If possible, sit forward on the edge of the seat. Water collects in the back and only drains when the boat starts up the first hill. You can get a wet butt before the ride starts ; )
Go, it won't be that bad.
