Very, Very Close!!

What a journey this Swing set has turned out to be. You would think I was constructing a 200 story skyscraper! Well anyhow, it is almost finished. This last weekend I received some help from friends and neighbors in carrying the tower into the backyard, and standing it in place. That was an accomplishment in its self. Then I needed to attach the actual swing set part. That had a whole different set of issues. Regardless of the problems, it is almost done. The last steps include installing the accessories, like rocks for climbing wall, steering wheel, Bronco Rider, and stuff, then I have to put down the weed guard , install landscape timbers around the perimeter, and then finally the mulch. Whew! I'm tired just typing it, I can't imagine how I feel after I do it. I need some input from experienced landscapers. Should I go to the effort of putting the weed barrier under the swing set and tower (lift it up), or will I be fine just getting it close to the wood? Well I have created a little picture album of the journey thus far. enjoy.
