This is of no real consequence except curiosity, but I'm at a loss to understand what "park" means in the title. I don't even know what sense of the word is intended. Is it "park" like a city or amusement park that you visit, and the idea is that you enjoy a variety of different activities while you're there? Is it "park" like a ballpark, and the analogy is that sporting events take place there and each one of these topics is an event? Is it somehow "park" like a parking lot? Maybe "park" is a too-literal translation from another language where the corresponding word has a meaning that the English one doesn't? I'm trying to guess based on context, but none of these really seems to fit.
