Anyone build a wooden play structure?

Thanks for the info to the three of you. lafinfil, thanks for all the detail. Might head over to Lowe's or Costco today or tomorrow just to see if there is anything that might suit what I need. If I build the structure I will be using all store bought tire swings, slides or rock climbing walls and copying their design so there shouldn't be any chocking hazards. But, I will take that in consideration.
