Arena layout and markings
 

In the Arena and Layout Markings pdf, I think the color of the Corral should be changed. The red key and red corral are on the same side of the field. The corral marked red is in Blue's alliance station.

If the corral is marked blue, the it is clearer that Blue's inbounders gets balls from that corral.

My opinion is that it won't be confusing.
