Hope it's the bottom of the dip for you Newton...
...however, those of you in contact with herself on the FaceAche interweb timewaster might have seen the new 'dip' in the farmyard we have acquired. Seems a very old underground tank (probably a septic tank, but it doesn't smell at all) hadn't been properly capped off or better still filled, and today was the straw that broke the camel's back when she stood in just the right spot and the ground gave way. It's about 6' deep, 6' diameter down there, and the supporting top rubble/soil cover is all of 6" thick. I've been wondering why there was a damp soft hollow just there, but hadn't realised it was quite that deep! Luckily it's not where Newton parked his Maser, otherwise we might have found it a bit earlier and more spectacularly!!
