Recently, I saw a vintage ad for Loch Ness Monster at Busch gardens Williamsburg. It was fun, scary and creative. I went to YouTube and watched some more advertisements for older roller coasters. A lot of them were pretty incredible and were leagues better than most of what we get today. So please, recommend some old and fun theme park advertisements and I'll probably watch them.
I don't know if this qualifies as an advertisement, but segments of the Banana Splits show were filmed at Coney Island in Cincinnati and Six Flags Over Texas.
Between H.R. Pufnstuf and the Banana Splits, the Boomers never had a chance to turn out normal.
