Yard. The picture above was taken from high atop the other end of the back porch roof on the day of the "N" photo shoot.
Most of our yard is planted with things other than grass, and a lot of the rest is wooded ravine which we've never been inclined to change. It takes about ten minutes to mow with a push mower and that's the way we like it. It takes longer to get the mower to the grass than it does to actually mow the grass. Hm, perhaps we could plant something else in some of those places...
When the kids were little, there was a large patch of grass on the east side of the house -- the back yard -- where they played and where we installed various sandboxes over the years, combination picnic/play tables and lawn chairs of all sizes, plank-and-sawhorse "balance beams." The biggest back yard attraction for the kids -- all the neighbor kids as well as my own -- was the playhouse that DH built at his earliest opportunity, which wasn't until after he re-built the stone retaining wall that he had toppled over early that first spring (it took 'til November and just don't ask).
When the kids outgrew the play tables, we built a garage, then a deck (and then a pergola over the deck) on their back yard. There have been a lot of changes to our yard over the years, always striving for improvement and better use as we all change and grow.
