Enter the best entertainment three kids (and their friends) will see...

until, of course, their new sister arrives.

Two guys usually install the structure, but one called in sick, so Trevor helped with the minor details until the guy's cousin could come help out.  So official.

We watched and played and watched and played (and worked on the basement) and played...

...and peeked...

 
And when it was finished the kids were in heaven!  Until, of course, it was time to come in to eat dinner.
