(A Welsh hill was upgraded to a mountain after three walkers found its official measurement was just too low. Mynydd Graig Goch in Snowdonia was originally measured as being 1,998ft (609m), but the walkers found its true height was six inches over 2,000ft (609.75m). Shades of that 1995 film set in Wales, which starred Hugh Grant as The Englishman Who Went Up a Hill But Came Down a Mountain. So you see, size does matter and a couple of inches can make all the difference. )
