I know I am besting a dead horse but the water smells and the chain grease smells are heavenly.  Scents are so heavily rooted in memories and I have such lovely memories tied to those smells.  I would definitely buy those candles!

Chain lube, Sweete Shoppe, the Area Formerly Known as Coney Mall around Coney BBQ, paint on wood and metal railings in the sun, and WWC when you are on the back part of Diamondback.

Please, though, no sweaty butt smell that arises on a humid day in a crowded queue like The Beast.

 

Nothing beats the fountains on IS right when you enter and dodge the "paparazzi".  It is the sense of "you've just left the real world.  Enjoy the day."

Sunscreen and pizza

I love the smell of the water shooting up from the fountains as you make your way thru the front gate. Someone else mentioned the smell of chain lube as you're waiting in line or actually on the ride. The smells of the fresh fudge being made on International street, the smell of skyline chili, and Larossa's pizza in both sections of the park(International Street and Rivertown).

There are so many wonderful smells at Kings Island.  My favorite is definitely the chain lube on wooden coasters.
