Now might be a good time to start collecting short pieces of steel tubing (say, 20"-30"), nuts, bolts and other scrap steel. Maybe toss in some scrap aluminum and brass too, maybe some copper....just to make things fun.
So when you bury that PVC tube, you can "salt" the surrounding area with enough false positives that it'll make the job more difficult.
On this day, twelve years ago, God answered a bunch of prayers, only a few of which were consciously spoken. He blessed me with a perfectly imperfect child...
