Hey chad I think you and I are on the same page for the most part with this idea. We must either not understand eachother or its the communication barrior of the Internet.....oh well. Anyways, here is my idea for the first scene and a rough idea for the rest of the ride. It entails four ride tracks but of coarse that is EASY to change......
1) Boarding Area.
Looks like a warehouse. Along the walls are propane tanks and spare parts for the vehicles. Sitting in a 'pit' (hard to explain but like a pit you would be in to fix a car) are FOUR 'SW-7s' (Storm Watcher-7, lucky seven.....). They are situated like this: Two on each side of a platform like that of Indy and Dinasour. To get to them you walk down two flights of stairs. Cast Members load all four vehicles at once, all four depart at once. They 'quickly' (frantically) leave the loading area into the warehouse.
2) Scene 1: Ware House
They take a few turns dodging shelves of parts ect. The vehicles are slowly split up but still visible. They are seperated by random parts and propane tanks. Soon, the lights in the warehouse go out to a loud clap of thunder. The engines stall on the vehicles. The smell of gas fills the air. Over the sound system "WE HAVE TOUCHDOWN! REPEAT! TORNADO IS ON THE GROUND!" Shortly the engines, one by one, start back up. One vehicle lets out a little spark and there is a small flame that is seen rushing toward the propane tanks. Over the vehicle sound system a frantic voice yells to get out immediately. The vehicles rapidly run toward the 'exit' as an explosion is felt from behind simulating that the warehouse goes up in flames.
3) Overall idea of rest of ride
The vehicles run side by side for a while dodging debris. Debris ranges from fire hydrants shooting out water, wrecked house parts, tipped trucks (basically anything you would see at a ground zero of a tornado strike). While dodging debris and eachother the vehicles seem to slowly split up. Each vehicle goes its own way and sees the tornado. Over each vehicles sound system you are told the other vehicles are slowly being lost to wrecks (of coarse this is not true). You see the vehicles 'wrecked' (dumby vehicles). The ride concludes in the rolling house effect and the vehicles making a mad dash for the "secure location" of a concrete reinforced compound. It is here you disembark in seperate locations, so that you never see the other vehicle. The vehicles also have different ride times so that when exiting you don't see the other people immediately.
Well what do ya'll think? I know you want the propane thing different but I think with it at the begginning it gives the sense of ergency to evacuate the "security" of indoors. Also, it starts the panic quickly to make the debris dodging more random and more frantic to really tie in the "lost" theme.
Oh and Chad, I am an Architecture Major at Texas Tech University.
