I definitely started out in the "Enginerd" camp. Like Hixee, I fondly remember visits to Cedar Point to just watch roller coasters in action. I had a passion (and still do) for model railroads growing up, and roller coasters became a natural extension of this. This was my initial draw to roller coasters and amusement parks.
Since that time, I have moved to the "Roller Coaster Enthusiast", "Social Enthusiast", and "Historian" parts of the spectrum. First and foremost, I love riding roller coasters. It is such a fun experience, and one I have really treasured over the years.
I also love being with people. And when you live next to America's Roller Coast, it becomes the social hang out, especially while school is in session. There were visits to CP where the one ride ridden was the Witch's Wheel, or we would play $20 worth of skeeball. Visits were not for the roller coaster, but rather the fun venue to hang out with friends.
I also love history, and understanding the background of places and events. While amusement parks have modern day attractions, they didn't always. Rather, amusement parks can be a great case study of historical change, often reflecting changes in technology and society as time marches forward. If you haven't noticed, RF II is my favorite roller coaster overall. This is not only in part because of the very good GG layout it sports, but also heritage to the original Ravine Flyer, which also spanned over Peninsula Drive. What is the greatest roller coaster of all time? While the coaster enthusiast would argue for Helix, Outlaw Run, etc.; the most likely answer is the Coney Island Cyclone. While the roller coaster does not sport the best layout, there are still historical connotations of the ride that transcend just how the roller coaster rides.
So bring those all together, and I am happiest when riding a historic roller coaster at a park with friends.
