Roads as Runways
There’s a 4km road that was certainly used as a runway from time to time in the 1980s, running south-east from Leszno in Poland to the village of Rydzyna. If you’re ever in the area, maybe visiting the Polish gliding centre at Leszno, do include a stay at the magnificent and atmospheric 17th century castle at Rydzyna. It was being used mainly as a trade union centre, albeit a pretty elegant one, when I was there then, but is now open as a hotel and conference centre.
