The road wound through the trees and followed the curve of the river so that they could not see very far ahead. The visibility was further restricted by the high bushes which bordered the road and the river. They were driving slowly along a particularly narrow curving section of the road, when Bob saw another car coming around a bend just a short distance ahead. Bob slammed on his brakes. It looked as if there was going to be a collision, for the other car was approaching very rapidly. There was no room to pass, for the river was close on one side and the other side was marked by large trees.
