Answering your question, You must find the RCT3 file which holds all of the programs information. click on it and you will find more folders (campaigns, coasters, parks, effects ect.) You will want to open the folder parks. Then just drop the file into the folder and you are done. I need to add that you need the Top Gun scenery and steel worx installed too. You can find these on this website under articles, then click on Rollercoaster Tycoon 3. Find RCT3 custom stuff and cheats. Get the Top Gun Theme pack, steel worx and anything else you might want.
