Where all da milk at!?

Howdy Cheesemakers!

I got into making cheese about 10 years ago and made some delightful stuff. Life got in the way and it's been quite a while since my last batch. I don't actually ever buy milk for drinking and the only time I do is for the odd recipe or the once in a while homemade ice cream, but I was perusing the milk at the grocery store last night with cheese on my mind and quickly noticed that all the varieties and brands of milk available are ultra pasteurized. Even the more regional organic brands.

So where am I supposed to get milk now? I recall way back that Costco brand milk was still a source of not ultra pasteurized milk but I didn't look last time I was there. Are there still any nationally available reliable sources for milk?
