Well, that amature & not-all-that-great Horsecreek Productions came out w/ a new DVD right here called:
Front Seat Thrills! 2 (
the cover looks like a very piss-poor photoshop job) which includes a lot of POV vids including Hulk, Dueling Dragons, a bunch at Dorney, Great America & others as well... some have no sound as they say they're stock footage, which goes to show you how much effort they really went into, into making this a quality production.
BUT... if you want Islands of Adventure coaster POV's, here's where you can go.
