 Rumours had surfaced that developers might purchase the track so the Irish Greyhound Board acted quickly and bought Harolds Cross in 1970 to quash any future re-development plans.The Corn Cuchulainn for stayers was another major event introduced to the track in 1961 and in 1977 the track went ahead with considerable improvements that included a new stand, restaurant and other facilities.The 1978 running of the Callanan Cup and Oaks did not take place at the Cross with the latter switching to Shelbourne.
