The Farm II Raceway has mainly dirt, but has a part that has grass, a part that has concrete and even a sand pit...truely a different track that will be the site of the 2008 IFMAR Worlds and the 2007 ROAR Gas Truck Nats!
This picture was from March of this year after a rain storm and the last race there incorporated the back part of the track that had about 60' to 70' of grass area that very quickly wore down with all the gas 1/8th scales and truggies that race there!
