All we really must have for the filming area is an area of trees [thick enough so that you cannot see through them] and enough space [1/2 a city block is usually plenty] to deploy the troops. It is not necessary for all angles to work. However, there must be some angles that do work. Modern features [cars, highways, power lines, playground equipment, etc.] are not wanted in the filming angles. Features such as rolling hills, dirt roads, old buildings, stone walls, rivers and lakes, rail fences, ditches, rough-looking ground, etc., are a plus. The ground must be inspected for safety. Areas where there is broken glass, barbed wire, dangerous animals, etc. must be avoided. Battlefield features and season of the year are considered when choosing which battle will be recreated. Parks or individuals usually donate the use of their ground. Their permission must be obtained. Time, money and transportation scheduling problems can be minimized if the ground is close enough to march to and from the school. Adequate parking, access and restroom facilities must be available. The battlefield must be left as clean or cleaner than it was before the event.
