Dad vs Daughter - Heat: Rocky Roads Expansion

About Heat: Rocky Roads, from BoardGameGeek:

The desert heat is relentless but so are you... Gravel sprays out from under your tires and your car gives a sickening lurch as it begins to spin out. Clutch. Shift. Gas! Your engine roars and your car leaps into the next turn on a perfect line; you're still in the race but you'll have to watch for loose gravel on the track. Heat: Rocky Roads introduces two new racing tracks. In the South Africa Grand Prix you will face treacherous gravel on the track, requiring careful management of your car and nerves of steel. Victory on the Germany track will hinge on how you deal with the fast pace of the newly build chicanes along the long straight away. Take part in the 1966 Championship season and take advantage of a new innovation, the sliding Skirt, to surprise your opponents and slipstream to victory!
