I think we should have these towers about 200 feet up in the air. That have small gun mounts on them. Not concrete or anything like in the city, but like a high area to see from the ground. Preferably 2-4x20mm guns on these towers. Plus if HTC made the main arenas have a night time you could then mount a light on these towers. Place these probably behind the main pad or any preferable place where planes wouldn't collide into them taking off.
