There's just one last animation to complete before this section of the project is finished!
Go to time 5;00. Select the LA HI-RISE text layers, press S to display their Scale properties, and add a 100, 100% Scale keyframe to each layer.
Go to time 9;29, and change the Scale property for both layers to 130, 100%. This will slowly expand the title horizontally, similar to a tracking effect.
