re: Sprinkler system for 0.5 acre yard...

It's way up in Indiana, but we have about .6 acres of lot, with planter beds surrounding the peremeter of the house about 3-4 feet.

We paid 4k for the yard + landscaping beds, premium heads and closer spacing. I thought it was a good deal. I sat on the porch and watched the Mexicans throw it together. surprisingly little damage to the yard when they were all done too. I expected it to be all torn to shite and messy, but you could barely tell they had dug trenches at all.
