No offence meant, Gerald, I'm probably 'nitpicking' and also in danger of straying off the topic of the airfield which lead to the building of Castle Vale and then we started discussing the surrounding estates. As I understand it, Chelmsley Wood Estate starts at Cooks Lane, Bacons End and then runs east to Bickenhill Lane. Green Lane is west of this and Smith's Wood was later built from Bacon's End and runs west to Green Lane.
Yes, although I never did the walk, I remember the lane past the sewerage farm which I cycled most Thursday nights to get to the CTC club meeting at Minworth village hall. Cycling alone down that lane on the dark winter nights could be a bit scary for a 14 year old.
