If anyone is interested I have just completed adding sound to my track "Westwood Racing Circuit 1967" (west1967) using the RaceCon utility. This utility makes it easy to add sound. I just became aware of RaceCon a few weeks ago. I added sound to each speaker pole, grandstand, the control tower, and the bridge.
Also, there is a small flaw on one of the edges of the grass textures that makes a noticable line where the texture repeats. I want to fix this. Of course there are other things I would have done differently but I'm not going to change the track at all. I would also like to add files for the 67 spotrscar mod. I'll look into this as well.
I'll upload the files when all changes are complete.
