Yes, it was apparently seen more cost-effective to divvy the runway up into 4 armco-barriered sections to stop kids racing their Cortinas on it and risk murdering aircraft in trouble than to secure the boundary gates against said Cortinas.
All because of the pompous prats in literally the only couple of houses overlooking the field who objected to kids having fun in Cortinas.
ps. I was one of those kids, though with a National 100 Kart. One of the residents got incandescently irate with me despite being barely able to hear the thing.
Utterly insane.
