There is a large area of overgrown grass between the woods and the motorway - now partly covered by the Soccerworld complex where football/rugby fields could have been. Others make mention of football fields further west towards Barlinnie. If you look at the Google map image I posted earlier, there is a rectangular shape visible underneath the grass at the top of the hill at the east corner next to Stepps Rd and the J11 exit.
I got out and took another photo of the motorway for a then now comparison with Alex's other M8 photo from circa 1980
Many thanks to Alex for posting the original older photos
[the photos are actually cropped at the sides for some reason when they appear on the forum, sorry can't work out how to get round that]
