I was using cassembler's thin roads when I noticed that I could not see them very well against Sn00py's terrain. What I did to the roads was add a whole new texture to them. They not only look better than the very original roads, but they are also easier to see against different terrains you might be using.
I also do want to thank cassembler for creating these thin roads. They look good no matter what the texture.
