The scenery "proof" shot shows the paved and dirt roads at Railfan Rock on the Jallen causeway from the second BC&SJ layout.

The spackle job for this area was shown in Roads - 1.

Again the dirt road is made with real dirt. The more I do dirt and dirt roads the more I've come to believe that it is important that the base scenery paint and the dirt used on the roads be color matched.
