What do people reckon.

If I was out thinking to myself there's some lovely blackberries up by those old stones, I'd be cross if someone destroyed a perfectly useful bramble bush, but if it was nettles would'nt mind..
The question as to whether a landowner has a civil duty to keep a scheduled monument on his land in good nick thereby ensuing its continuity yes; but for the general public probably not....
Have the same problem with loads of bolshy bullocks on the Cotswold Way ;) terrorising a particular collie and its owner... someone though has knocked some stone wall down to escape said rampaging creatures... who is right in that instance? the walker who has a legal right to walk a public footpath, or the farmer's right to keep cattle in his field....
