Why are we sprinkling flagstone?

Good question!

The sprinkler (and the pipe to the left) need to be protected so I was
figuring I'd lay the flagstones along that wall as a walkway.

When complete, the sprinkler would be within two inches of the edge of
the flagstone, and it would be sprinkling the grass.
