Hi, We are a group working with Severna Park High School on an Engineering Design and Development class project. Our area of interest includes arrows becoming stuck in plywood backstop while target shooting, and we are now collecting market data. Over the year, we will be attempting to solve this issue. If you could take our quick seven question survey to provide us with some information, it would be much appreciated.
