Gordon Lewis scores Riverton's only try in their loss to Nightcaps in 1976.....

The first game of the Central Western championship in 1976 saw Nightcaps beat Riverton 9-4.
It was Nightcap's Geoff Valli that made the win possible by scoring all their points.

Riverton had the most possession with Philip Laurie and Philip Ward starring in the lineouts and dominating in the loose. 
Both teams were guilty of mishandling the greasy ball but Nightcaps deserved the win and were definitely the better team on the day.
Nightcaps:  Geoff Valli, (1) (1Con) (1Pg)
Riverton: Gordon Lewis (1)
