Thirty years ago, they helped organise the first rally, to which about 30 people turned up, and they never thought it would grow to about 50 times that size.
''For the first one, less than 30 people turned up and we thought that was pretty cool, then, for the second, 250 people turned up ... we didn't know what to do,'' Mrs McKie said.
This weekend, 1350 bikers and 150 volunteer crew from around New Zealand turned up to camp in a riverside Galloway paddock, take in the Central Otago scenery and listen to live music.
''Back then we only had a car stereo with a tape ... we still got noise complaints,'' Mrs McKie said.
Then, they camped at Fraser Domain, near Clyde.
She said it was chosen because her family had camped there since the 1960s, so she knew it was a nice spot.
''And it wasn't in winter. We didn't really like the Brass Monkey [a gathering in Oturehua in early June] 'cause it was too cold and that was really the only other rally then.
''Our motto was `you froze 'em at the Brass, come roast them at the Vincent.''
They were cautious, though, because of a stigma about bikers.
''There was a stigma about motorbikes at the time and we were quite conscious that there had been a lot of gangs ... but the first one was so good we thought we had to continue.''
Within two years, it had far outgrown the domain and moved to the site at Galloway.
The three said while aspects of the event had changed and developed over the years, it would always be a gathering of like-minded people, motorbike enthusiasts, who also kept returning to catch up with old friends.
''Sometimes we only see them once a year,'' Mrs McKie said.
Bronz (Bikers Rights Organisation New Zealand) Otago president Mary Storey said proceeds from the event would be given to the Muscular Dystrophy Association and the Otago Rescue Helicopter Trust.
