If you build it right why do you have to climb over a "jungle gym"? What will covering the bars do for you? It is only going to the same height as the bars or higher if you space it over the bars.

I just don't see the point in the time spent whether you are paying someone or doing it yourself. I guess if you want to impress people looking at it then it would be worthwhile. I would rather spend my hours that I would spend doing it doing something else.
