i remember climbing haystacks in the western fells when quite a small child , and standing at the summit looking down upon calm inominate tarn , where the great man of the lakes alfred wainwrights ashes were scattered , and thinking , at the time , what a tremendous height i had achieved , and then realising that i had actually scaled an equivalent vertical height , by walking in eternally reducing concentric circles , up , up , up the outside of the wendelson building in pyongyang .
