Well, no need to go THAT far! 😀
Ref Ump Welsch wroteI was imagining a fence that was partially collapsed at the top, not one that was prone to the ground. What you quoted, I would have covered with a ground rule (or try to put the damn thing back up before the game if I have time!).
This was not entirely hypothetical. In a national tournament (not ASA...) they were using temp fencing. It was a very windy day, and a section of the fence blew over to the infield side. So, the fence was prone to the ground, laying in live ball territory. My partner and I did try to prop it back up, but the wind would just blow it over again. Fortunately, the strong wind in meant a HR over the fence was highly unlikely (read: no possibility!).
