I am in your shoes!! We are getting married two days after you, December 5, 2009. I have also been getting nervous about the weather, but as everyone else said, you can't really guess what will happen. We wanted the 4pm time so that we wouldn't have too much lag time between the wedding and ceremony. From what my fiance and I have discussed, we are going to stick with the 4pm slot and hope that everything works out! I would be more upset if I made the wedding earlier and then it still rained!!
