Dumas sits isolated on the flat, open plains of Texas, where the horizon stretches wide in every direction. The Dumas Grand Prix threads through this town, tracing a 2.9 mi loop that passes beside the First Presbytarian Church Dumas and the Come As You Are Church. With 18 corners, the circuit requires a steady hand and precise transitions to maintain speed. It is a moderately technical layout that plays free in the browser with no account and no install, testing whether a driver can keep the car balanced through its frequent changes in direction.
