The right and only call, sadly. When sturdy Portaloos are flying over you know it is too dangerous to be in the woods. With Alpha flooded , it would have taken hours to become safe again.
Lousy call to make, but you had to do it. Don't think anyone would be too happy with a bloody great branch crashing down on them.
I'm sure people are just disappointed and were raring to go despite the conditions, but really it wasn't shootable, no matter how keen you are.
Better luck next time, I guess.
