We all like the see the outside of curves .
It also is a vantage point for great photos and glimpses .
Ease of maintenance is a plus .
Plexiglas's , Maisonette , or modeled in berm guards are usually not removable . Snap up Plexi , screens , or whatever would be ideal if they lay flat and upside down when unwanted , and snap up to a forty five degree angle when used as protection . Each unit needs to only be a foot or less long and at the raised 45 degree in use position be just a few inches high .
