More than 500 truckloads of dirt create the Houston Livestock Show and Rodeo's center stage. And this isn't your everyday potting soil.

Grab your cowboy hat, Houston. The Houston Livestock Show and Rodeo kicks off Tuesday. Why it matters: For the next three weeks, Houston's universe will be circling around all things rodeo — from the concert series to only-at-the-rodeo carnival food and more.

When the Houston Livestock Show and Rodeo is open, there are as many people on the grounds as there are residents in the entire City of Pearland.
