The large post takes the place of a concrete post that was originally there and had the washing line attached to. Rather than fill the hole, I put a new wooden post in and used it as an anchor point for the decking frame.

Shoulda made it a bit lower, wouldn't need to have built the steps then!
There's a walkway near my house that goes over a marshy bit of ground that is made of decking planks. It has been closed off twice because it's impossible to walk on it whenever it's wet. The first time the council stapled chicken wire to it to improve the grip but, of course, yoofs started pulling it off and were causing near invisible trip wire hazards. Council then closed it again and have left it that way.
I'd recommend you get a couple of cheap Workmate type things next time to put your mitre saw on. I have mine sitting on one on a bit of old worktop and the other one is to rest the other end of long bits of wood on. It'll save you bending over on the ground and getting a sore back!!
