How can I display the grid so I can see it on my terrain?

I want to be able to use the grid as a guide for measuring timeline animations, but I can't see it over my terrain. Am I missing something simple? I can see it beneath the terrain, but not over it when I'm editing the timeline animations.

For clarification, I can definitely see it and when I lower the Y transform of everything, then the grid is visible. Guess I'm really wondering if there's a way to raise the Y transform of the grid instead of lowering the transforms of everything in my game.
