Well, I've never really read much H/D as I'm not that great a fan of Draco at the best of times, LOL, so Snarry was my first foray into reading HP fanfic and then writing it.
I loved your story Snape the Home Fries Nazi and I agree with you, that although you plonk them down in Arizona with no magic, it did seem canon-compliant to me.
Most of my stories tend to be AU of some sort or another as there are so many things in canon I don't like :)
