Who looks for their ball in that shit? It's just lost. It shouldn't take any time now. Play a provisional and on the off chance it is on the edge and you find it, cool. Otherwise, continue with the provisional.
I think this will lead to too many areas being marked, and your suggestion that ALL tree areas be marked is still ridiculous IMO.
I agree that it (lifting) is a part of other actions however Rory's foot does come up in the swing you posted. It would not have rotated like it did if all his weight stayed loaded on it. The forward and upward momentum of the aggressive shoulder turn brings his foot up.
Can we find a jock strap image?
And about the weather, sometimes it rains in NC in October. I'm guessing that for some of those fellas from sunny southern CA, playing golf in the rain will be a rather foreign experience.
