Trust me - when I did my research for my Road Trips, I really did some fine-tooth combing. So when a new-old park pops up that I didn't know about, I'm simultaneously humbled, intrigued, piqued at myself, and raring to figure out a way to visit it whenever a Road Trip II is in the works.
Take a peek at Martin's Fantasy Island! It's near Buffalo, NY and has been around since 1961! With the exception of the antique cars and tilt-a-whirl, it seems that most of the rides are newer, but still it maintains a definite vintage feel!
