When in a park that can build six flags scenery, place a line of metal framework (you can guess what I'm talking about) down on the floor. Then place a roller coaster on top of this and you should notice it doesn't cost you anything,(you're actually given money) each time you place it down over it. Then delete the roller coaster track to get the normal cost of the track piece back. You should get a total profit of about $60 (taking away the cost of the scenery) for each piece of track you place and delete. Make it as long as you can each time and repeat it over and over for as much cash as you want!

Great for completing Six Flags Parks. (Especially Magic Mountain where you can gain enough funds to repay loan before park value drops below what is needed.)
