I couldn't agree more. As much as I love Kings Island, I wish cargo falls was near the other water rides. Rumor is Carowinds is getting a water ride next year so depending on how that goes, I could see Kings Island getting one of those to replace Congo falls when the time is right.
Someone already mentioned this, but I'll say Delirium is my favorite at Kings Island. However, last year when they introduced Cargo Loco and Sol Spin, those were huge upgrades for the flat ride department at Kings Island.
