I was at Sandwich on Thursday and Friday and was surprised at the poor scoring and generally poor short game that I witnessed. I played at Deal Friday morning and it was gorgeous yet the scoring down the road did not reflect it. Mickelson putting from 20yds short of the 1st and leaving it on the edge of the green. Cabrera thinning a wedge through 7 and taking 3 more to get down. The following day Cabrera hit an 80yd wedge fat into a bunker, as did someone in each of the preceeding groups.
Scott is right about the south east being dry, an average wind is 10-15mph or a couple of clubs. It's rarely still and rarely more than a 3 club wind.
