LoL!

I think I'd be too scared to drive with a roof rack, I have refused to drive with a trailer previously too x_x

That was fortunately the only time for us, the rest of the time the herd was elsewhere in the paddock (we could usually see them), and the job only took a few days in total. The other entertaining incident we had was trying to herd a stupid lamb back into the paddock, it had gotten out through a gap in the fence and was desperately trying to get back to its mother and was apparently too dumb to go back in the same way. I tried to just grab it but it wasn't having a bar of that, so we opened the gate and then chased it through before opening the gate the rest of the way so we could drive the ute in. That was much more entertaining and less terrifying than the bull XD
