Raw Milk for U.S. Visitors?

 My husband, pregnant daughter, son-in-law, and I will be visiting the Oxford and Cambridge areas of the UK from Dec. 27 - Jan. 7. Is it possible for us to buy a couple of gallons or so of raw milk while we are visiting? If so, where would we do this? Are there any farmers in these areas who have extra milk? I am a Weston A. Price Chapter Leader in Colorado, and we really like our raw milk. In fact, we're so spoiled that we don't want to go without while we're on vacation. And given that our daughter is pregnant, we're trying to help her get the best nutrition possible. Any help is appreciated. Thank you,Nancy
