KI was built when there were only 4 or 5 TV channels, no Internet, cell phones, urban sprawl, etc. The world has changed very much since those days. KI used to be a unique amusement experience in the middle of a very pastoral setting. Now, it's a cookie-cutter park in an interstate corridor, surrounded by expanding growth and development. It used to have soothing, up-beat and melodious music that gave the feel of being in a very special place; whereas now it pipes in music you can just hear on any radio. The theming and ride-name concepts connected the park to its southwest Ohio heritage. It feels more like a giant, expensive carnival now.
The culture is much different, too. In the early days of KI, you didn't see and hear so much of the rudeness, sarcasm and disrespect as you see today (people running, line jumping, or imbiciles mouthing off to staff, security, etc.). Families were much tighter, and many more people respected and understood the concept of common courtesy than these days.
KI is still a nice escape from the real world; I just wish the negative stuff of the real world would disappear once everyone gets through the gates.
