I'd take a fairly small roller coaster...say Comet from Hershey or something like that...and put it on my college campus, near my dorm. That way, I could randomly go out and ride it whenever I wanted to...midnight, before class, after class, take a break from work, whenever i need the adrenaline rush, to celebrate getting a paper done, that sorta thing :-D
Haha no I'm not giving Patrick the finger
