Excess enthusiasm causes irrigation line holes

After two weeks of exhausting work-related travel, I eagerly headed outside yesterday to plant some raspberry canes that had arrived by mail a week ago. They were overdue to be planted, that's for sure. I ordinarily use a pulaski-like hand tool (see photo) for my digging work here, because, unlike WI, an ordinary garden hoe would break in less than five minutes with this hard dirt. The difference between the tool in the image & a Pulaski is the pointy end, which replaces the axe portion of the Pulaski.
Irrigation lines are the underground tubing that delivers water to the sprinkler heads scattered throughout the yard. Many homes in this part of the country have automatic irrigation systems due to the need to water to keep turf reasonably green. Annual precipitation in the San Luis Valley is only 7 inches.

Since I've had problems NOT missing irrigation lines before, I thought I'd learned a lesson, and have tried to be careful when using the tool . But the irrigation line that I hit yesterday was a mere 6" below the surface - way too shallow! The puncture holes are visible in the black tubing in the image - there are two of them right next to one another. The ruler is there so that I could figure out what size of connecter to buy to replace the damaged segment of tubing. (Since this has happened three times before in summer of 2007, I'm somewhat familiar with the repair process .....)

So I had to trek into town to visit my favorite True Value hardware store (favorite because of all the connecters I've bought there before....). The parts needed to repair puncture holes are shown - the flash drive is shown for scale. The only additional tool that's necessary is a hacksaw to cut the piece of damaged tubing out. Of course, this means that the hole in the ground needs to be enlarged to accommodate the hacksaw. The process of planting my raspberries, which I could have completed with ease yesterday, will now be extended into a good part of today. *^&$%@!#(%
