Woops, looks like Rob beat me to it.

Also, if you know the distance, you can somewhat know the next target, but remember that after every end (2x arrows I think?) you pull those targets and then move down the line to the next shooting station. I think there were 14 spots to stand at through the line.

Here is another pic of the shooting line and crowd watching. You end up shooting from each position that you see a guys standing here, so that helps to mix things up quite a bit.
