Goodbye, sandbags. No need for bags, pins, or weights. They stay put in high winds without stakes or sandbags. These are the famous baseball tarps that are used by every level of baseball: Little Leagues, High Schools, Colleges, Minor and Major Leagues. Chain in the entire perimeter keeps wind from getting under, so they do not move or blow away. Remarkably, Wind Weighted Tarps have encountered hurricane force winds and did not move from the mound and home plate.
