Been kicking around building a wood deck for a few years now and looks like we might be moving forward. It has been many years since I have done one. Anyone have a decent amount of time on them? I'm not interested in composites, just good ol PT wood. I'm sure I'll have a few more questions, but my first is what wood do you perfer? 5/4 deck boards? or 2x6's? I'm leaning more towards the 2x6's. What spacing do you like? 16" on center? Do you lay plastic on the ground under the deck? Never done this but someone suggested it. What spacing do you like for your footings? Every 10ft?
