We are considering a trip to Half Moon Bay in mid November. Any concerns with the weather? On a previous trip we were there in late October and had wonderful weather. We already know where will be staying so it is just of matter when to come. We ran into the Pumpkin Patch traffic on our first visit to HMB and it took us 1.5 hours to get down the drive. It will be just my husband and myself. Our plans are to make HMB home base and do day trips from there.
