Danny: fear not Mrs. W, my memories of 53 yrs ago paint places in a rosier glow than they have today!
Chelsea tractors: many or most cannot use their capabilities, and when one loses two tons of tractor it takes considerable room to get it back, as I discovered in 14 years' LWB Land-Rover operations. And few realise that their massive go-anywhere 4wd has only as much traction as the 2wd saloons stuck in line up the hill ahead.
I flew from a light snow layer one day. Taxi and turning was no problem, but when angled across the taxiway to run up the park brake had no effect whatever and I throttled back PDQ. When I tried to push the brute into the hangar I fell flat on my face. Serves me right for not following the national line and Staying Inside in Snow.
