For more than 50 years, this historic roller caster in Missouri has been taking riders on extreme and intense rides.

The River King Mine Train at Six Flags St. Louis has been around since 1971 and at first, had side-by-side tracks. One of the tracks was sold to the Dollywood theme park where it was in operation from 1989-1998. It was then moved to the Magic Springs in Hot Springs, Arkansas, but the Six Flags mine train is still in operation today.

The ride reaches up to 37 miles per hour while moving through a series of dips, dives, and turns. I am not a big coaster rider, but every time we visit Six Flags this is one coaster that I can enjoy even with that 14-foot drop in the dark.

Stacker hunted through internet resources, pop culture publications, and databases like Know Your Meme to find 50 different memes and what they mean. While the almost self-replicating nature of these vague symbols can get exhausting, memes in their essence can also bring people closer together—as long as they have internet access.
