Forgotten Houston for Kids: Peppermint Park
Why did it disappear?
Like most things of this nature, I'm sure it was just the nature of the economy. With more entertainment options available and newer, bigger adventures, the Peppermint Parks just kind of died off. A Wikipedia entry says the one in SugarLand was open until the early '90s, but the others closed much earlier.
What replaced it?
Nothing. As far as I know, there are very few micro amusement parks like these. The closest would be the carnivals that occasionally set up in mall parking lots, the Kemah Boardwalk and the Galveston Pleasure Pier, but those are huge compared to Peppermint Park.
What is there now?
The Gulfgate location just merged with Gulfgate Mall. The SugarLand location became an auto body shop affiliated with the Jeep dealership. The North Loop location is now just a nondescript warehouse office building. Sigh.
