It's funny the conversations you can have with your nearest and dearest. We were sitting in Kirkby Lonsdale churchyard on our wedding anniversary dicussing the length of ladders! Is the stated length of a ladder its extended length or the height it reaches up a building taking into account the angle of inclination? Needless to say my confusion of some time was ended by the incisive wisdom of HS and now I can proceed with confidence - but still an element of caution as I ponder the height of bloked gutters and flaking weather boards. Every onwards, ever upwards!!
