Feld's dirt crew guys had to start moving in dirt last Wednesday, so this isn't just your average track (even though it kind of is in some senses)! These guys are far from your small promotions, where they just carve away at piles of dirt until the ramp looks good enough. They measure the length, angles, width, height, and more for each one of those ramps. They may have advertised two totally different tracks for racing and freestyle, they have to get a base started for practice, qualifying, and racing day so come freestyle day, they can add on top of where they started. But ultimately, they need to get all the permanent obstacles built come practice day, then freestyle day is when they can adjust ramp angles, ramp heights, and add cars, vans, RVs, and other crap out there at their and the drivers' discretion.
