@uliwitness Crashplan? Mozy?
I’m reasonably sure that’s the right vent I’ve snapped, but not 100% certain. Also: (a) I would not like to have been a construction pony, and (b) “pony in a tunnel” sounds suspiciously like slang for something I probably wouldn’t want to do, or possibly eat.
Black Rock quarry, Portway. “…in 1950 an old shaft leading out to the face of the gorge was re-opened after having been blocked for many years. Originally it had been used as a stable for ponies employed in tunnel construction.” — Colin Maggs, _Bristol Port Railway & Pier_ 1975pic.twitter.com/r11069Rt9TT
