Definite sympathies. I've lugged many a rock to our garden over the years, and I've learned to be suspicious of one particular kind of rounded boulder that is common in Tyneside. On the surface, they look like sandstone, so you think 'Oh, no problem' but they're preposterously heavy (which is why they're still lying about). When you try to carve them, it turns out that the sandy bit is a weathered patina only an eighth of an inch deep, and inside is a fiendishly dense grey stuff, very heavy and a right bugger to carve. Wish I knew what it is.

I know it's easy to become blaze about megalithic stones, when you've seen bigguns, smaller ones become nowt special. Then you try and shift a small one a short distance by yourself, and suddenly, respect blooms anew. If nothing else, for the evident community requirement when it comes to shifting even moderately big old rocks.

Good on yer HoD, it's a noble calling, and disparagement from the spouse goes with the territory ;)
