London speedway in 1970 was my first full season of visiting tracks other than Wimbledon. As a wide eyed youngster I was taken to four new venues that year. They were in visit order, west ham, wembley, romford and hackney!. The highs were, the dons winning the cup, Christer lofqvist's debut for the hammers, the lions reopener at wembley and the Czechs dicing with romford's notorious concrete safety fence!. The big low was the awful lokeren tragedy.
