Suggestion of either a trap door or 2x4s nailed to the floor around the perimeter of the entrance have been suggested. At least putting the 2x4s there, the player can feel when he's close even if he's facing outwards. Considering the number of games int he last year and a half at the LZ, and it's 15ft rock cliffs and 5 towers, this is the ONLY injury the LZ has seen yet. I'd say that's a great track record (yes, none is better).
