Only once had to alter plans for a day out on Sgorr na Diollaid when a notice at the roadside asked me to check at the Stalkers house close bye. On that day I had to go to another hill ......plenty to choose from above the nearby dam.
Notices on gates with phone numbers to check for shooting days.... I used to get a wee booklet with phone numbers for estates to check for shooting days.
No problems on Sundays when all the shooting folks attend church.
