I am sorry if this is an old chestnut. If it is someone will, no doubt, re-direct me to an old thread.
I've made a number of aeroplane journeys in and out of London Heathrow recently and I've been interested to see the considerable variety of mowing patterns used at different golf courses below me. There are broad stripes, narrow stripes, longitudinal stripes, latitudinal stripes, criss-cross, diamonds, wavy lines....
In his thorough way Tom Doak briefly raises the subject of mowing patterns in 'The Anatomy,' but does it make any difference to the way a hole plays if it is mowed differently?
