darcy and the cone of shame

If you've ever seen "Up!", you might remember the above title.

The dog got spayed - FINALLY. And THANK YOU GOD that He answered my prayers and it was free! The only problem is my 50 lb. puppy kept ripping open her incision so it's taken twice as long to heal, with an extra helping of antibiotics, a bandaged torso, and diarrhea...yeah being a dog owner :) But I'm very glad the vet's been nice and not charging to see her post-surgery. Thanks Guadalupe Vet Clinic! (and for being right down the street from my house!)

Now Darcy's pretty much all healed up, and I wanna take her camping on this, my last weekend of summer. (I can't believe training starts next week!) So now I'm at a loss as where to go!!!

This is where I actually want to go:
[thanks to longest acres for the pic]

But that doesn't exist in Arizona.  Any ideas on where I could go?  I don't wanna drive all the way up to Flagstaff, and I wanna end up somewhere coolER with water so the dog and I could go swimming.  Please give any and all ideas!
