Yes the gung-ho rock stack business elicited gripes in our house as well (though I was meanly gratified when he looked terrified when that bit of rock broke off). And P-P, why not get someone who was an expert on Orkney not drag in someone from stonehenge (with what appeared to be dubious connections) - it's not like there couldn't have been plenty of such people about. But I enjoyed it overall, all the neat stonework and corbelling and lovely landscape. So many places to think about going and it's definitely moved up the list.
