I just came back in from the yard. I'm covered in mosquito bites. Totally covered. I think I need to think about chemical warfare in the back yard. On the up side the sprinkler system I've been dreading testing all year appears to work just fine. There are a bunch of missing heads, which means digging and the like to fix them...but there is only one place where I suspect the line is totally trashed. This is fantastic news as we're having landscapers do the front yard very shortly here. The down side is I have to fix the heads in a hurry, so the system is ready for the new plants. It does appear that some number of the heads are actually outside my back fence... which was set where I believed the property line to be. Not far outside mind you but outside none the less. Stay tuned for the further sagas of sprinkler head madness.
