Ah, now you're getting your money's worth, what would a shooting trip to Britain be like without getting drenched?
Take care, do the best you can, dry out and oil every nook and cranny of your gear when you're done.
EDIT - I just read the team blog and see that Ray Smeltzer went clean for the day, moving him from 43rd in the Grand to 12th(!!). Wow, well-done Ray!!
