A riddle

Once again, the adventures of veterinary school have taken me away from the plains of central Illinois. Let's see if you can guess where I have been. Here are some hints:

It looks like this at the end of March

But when the clouds finally clear, there are some gorgeous sites

 The desert sagebrush...

and the mountains... not something you see in Illinois.

And everywhere you look, there are sheep! Even places you don't look. (And everything you see, including clumps of wool, piles of snow, and rocks start to look like sheep.)

(Warming up chilled lambs in a lamb jacuzzi)

Stinkers. Moms put up with so much.

(Getting weighed)

Here's another hint: It's a federal facility, so you can't ride in the back of the truck.

Me, Nicole from UC Davis and Melissa from University of Wisconsin.

There's also a real live veterinarian, Dr. Liz Adams.

She's a super rockstar.

Since there are so many sheep, you might come across something strange every now and then.

(two headed. He (they?) didn't make it)

Final hint: while I was here I was able to make my sister's birthday cake.  Thank you, David Lebovitz, for an awesome recipe.

And of course I visited this whipper snapper.

 Look at her awesome hair!

The end. If you still don't know where I was for the sheep part, I will give you a final hint. Ok, that wasn't really a hint.
