Bush Fire

So we have a deer problem here. Feral bastards jump the fence and eat the young trees we have planted. So we decided to raise the fences to keep the bastards out. So being a cheap arse, I am welding on some extensions on the start droppers. Good enough plan, but set the grass on fire and well if that got into the paddock of meter high grass behind us, well, it would have been a nice bush fire. It would be nice to have it burned and not be such a hazard, but I dont want to be responsible for it or burning someones house down. Looks like I need an offsider to keep the fire out while I weld.
