McGhie said the camp culminated in a match-up on Sunday evening between two All Stars teams selected by visiting international coaches: "Smarty Pants" from Texas and "Jackie Daniels" from the Windy City (Chicago).
The white team, Charolais Charge, and the black side, Galloway Stampede, each featured a River City Roller.
"I played for the white team and Emma Lamb (aka Empailer) was in the black team," McGhie said.
"It started out a fairly close bout, but the Galloway Stampede eventually drew out to win by more than 100 points. It was fun, though, and it was open to the public and there were heaps that turned out to watch."
McGhie said the next outing for the River City Rollers were home games in August for a three-way match-up involving teams from Hawke's Bay and Taranaki.
