So, there I am, lying abed reading about Soay sheep and sea stacks and puffins and what not, and the earth rocks at 5 point something on the richter scale (apparantly). Me? I feel nothing, zip, nada. It's dissapointing really. My conjecture is that the strata under northern lancashire is a sort of pink blancmange without the kirsch, or that Lancashire folk are just so hard that nothing under a force 7.5 would rattle our flat caps.
