There is no requirement that people wear shirts in the dry park. Three rides in the "dry" park don't require shirts to ride. WWC, Flume, and Congo. People can walk around without shirts, they just need to put them on before riding most rides.
I beg to differ. I have MANY times seen security direct young males to put on their shirts in the dry park, and yes, this year. In addition, "people" cannot walk around without shirts, as people includes both males and females. Well, they can, but not without consequences. See also Cedar Point's website (since Kings Island, like on so many other things, is totally devoid of relevant content):

There is NO reason to think Kings Island's rule would be any different.
The only attire required to be worn on WWC, the log flume, and (I assume) Congo Falls, is shoes. I am level 1 (fully trained) on both flume and WWC, so I know the requirements to ride. In the park there might be a requirement for shirts, but it's a rule that isn't told to ride ops, and I've never seen it enforced, and I don't feel it should be if they're going to allow people on the water rides without them.
So people can wear JUST shoes?
