Yes this is very true. I remember going go karting once to the Full Throttle Centre in Mill Race Lane in Stourbridge Town. In Quarry Bank, there was a fair amount lying snow albeit very wet (probably about 4cm) however as you lose elevation, usually as you then enter Lye or alternatively via the Amblecote road, Hillfields Road and then especially down Vicarage road towards the War Memorial Athletic ground, there was basically nothing on the ground then. All that difference in about 2 miles as the crow flies!!!
