Marching band doesn’t have a dedicated field that can be painted and used regularly. What’s great about the Porterfield system is the ability to move it to any open grass area that we want and we can use it in preparation for a show on campus or off. No more worries about painting or guessing when you’re rehearsing in an unfamiliar situation. It takes us less than 10 minutes for set up or teardown. I recommend this lining system to any college or high school marching band with a group on the move.
