Where have you been hiding these my whole life?

So when grandpa and grandma came a few weeks ago grandpa put in the sprinkler pipes so that the yard can officially go on auto pilot. A minor glitch in the system had dad out there for a bit to fix it. I subsequently found the sprinkler. WHOA! What a trip this was. I had a blast. Mom was not thrilled with the ensuing soaking but hey, summer is made for these things I would presume.
