Anyone want to help?

I'm really getting serious about our back yard.  I know we can't do it this summer, but we can do some planning, can't we?  Bill and I went to a wedding reception next door, and I just love their backyard.  I'm ready to start drawing up the design.  Here's the "Before" picture, and quite possibly next summer, you'll get the "After" picture!

Notice the pvc pipe stretched across the rock?  A couple of weeks ago, Will was pretending he was cutting down trees.  The pipe was the tree, and he would hold it upright, and yell "timber" as he let it fall.  Pretty creative mind.  By the way, no one was hurt during his lumber jacking :)

If anyone is interested in giving us some creative ideas for the design of the backyard, feel free, (unfortunately, we can't accommodate a pool, financially) so it looks like that is the only limit to the design.
