Well I used to load out of Running Waters Quarry with Lime for farms I used to go in on a Sunday & load for Scotland We used to load ourselves the key for the loading shovel was left on a ledge at the weighbridge, this was in the 70s, I got the work off a firm named Renwick Wilton & Dobson, & a lot of the loads went up to Blackridge near Armadale, Thats when money could be made without the hassle we have to-day, Regards Larry.
