Until the middle of the twentieth century many East Enders, and those who lived south of the river, in the poorer boroughs of London, went hop-picking every year. It was quite an industry and a practical way to earn a few pennies, enjoy a family vacation, albeit a working one, and breathe clean country air. Of course, the descendants of those hop pickers are now barreling down the motorway in their land cruisers, roaring past those old hop fields and disused kilns without a second glance, as they head to the Channel Tunnel and the promise of warmer, richer pickings on the other side.
