Sorry it took so long, but here are pictures of the pool and deck. I'm having some algae problems right now so the water is kind of cloudy.

I've still got a bit of work to do on the deck, like framing out the underside, putting lattice up for additional storage and some staining but it's pretty much finished.

My deck posts are set well below the frost line so I don't expect any heave on the deck. The pool, being buried 2+ feet in the ground hasn't moved over the past 2 winters (I measured several times a week against a fixed point on the house) so I'm keeping my fingers crossed that I wont have any problems with the rails sitting on the deck surface.
