SFSTL is actually not that bad of a park. No, I am not saying it because it is my local park, I like the arrangement of rides (except ninja) and we have few unique stuff. (Example: 2 sided log flume, Biggest Ferris wheel in all of Six Flags, and Xcalibur)
This is true!! Awesome rapids ride.. I have gotten bloody fingers and scrapes on it several times from being knocked around.. But it's a fun knocked around. I love it ha-ha..
I too have experienced some bruising to the legs and hips from being ricocheted when the boat hits a rock. It's great though! I've also embarrassingly choked after taking a water cannon directly in the mouth and nose.
I got that too on the log flume at SFSTL. Except it included my open eyes too
