Finally!

Here's a few pictures of the finished deck. I included a picture of the under-deck mountings I used for the floorboards. This way there are no screw heads on top, and less chance for splinters to form as the wood dries. I made a couple of amateur mistakes (it's out of square by an inch each direction), but overall it's rock solid and isn't going anywhere any time soon. It's a good, sturdy, safe place for my son to play, and that's the main thing.
