Drop Location I understand the the event coordinator is responsible for keeping all spectators at a safe distance to the drop zone. All spectators must maintain 200 feet from the drop zone and staff members must maintain 100 feet from the drop zone. The drop zone must have a clearance of 100 ft clear of trees in all directions. We request the drop zone be clearly marked so it can be spotted from the air about 500 feet above.
