How does one add text to a dark ride?

what do you mean, and on what game?

In roller coaster tycoon 3, I would like to add text to a wall for my dark rides to help explain some of my stories. I have a feeling that I could make text and add it to a billboard but i was wondering if there was an easier way of doing so.

If you're planning on creating a POV for this ride, the easiest way would be to add it in the video. It wouldn't show up in the downloadable version of the ride, but it would be easier to read than a billboard, and it wouldn't take up any extra space in the ride.
