On Saturday night (July 4), the Terminal City Rollergirls take to the flat-track for the league championships.

Four teams from around Metro Vancouver—Public Frenemy, Faster Pussycats, Bad Reputations, and the Riot Girls—are playing for the house team championship.

Pam Berg, aka Tiki Timebomb, has played with Terminal City teams since 2009, while also serving as a coach and head of inter-league relations.

“This weekend is what our entire house team season has been building toward,” Berg told the Straight. “We’ll have a double-header, two teams playing for third place, and two teams playing for the Mercury Shield, our championship trophy, which a team gets to take for a year.”

Looking ahead to this weekend’s action, Berg already knows the final bout will be a big win for this year's top two contenders, Public Frenemy and the Riot Girls.

“Public Frenemy has never won the championship,” Berg said. "The team has been around for five years, this is their second time competing. The other three teams have already won it, it would be really cool for [Public Frenemy] to get it.”

On the other side, the past two seasons ended with the Riot Girls claiming the top prize; now they aim to make it a dynasty with three consecutive wins.

"Either way, it’s super exciting,” said Berg.

Public Frenemy also skates into the finals ranked number one in the Lower Mainland; according to Berg, the team is also ranked 27th in Canada for house teams. Teams will often keep an eye on how a win or a loss could affect its position, though she says any changes in standings would be minor at this tournament.

“There are 126 teams in Canada; you have to play a couple teams to go up or down, it’s kind of tricky,” Berg said. “When you only play your own teams, you have to play someone else from another area to find out where you stand."

The sport of roller derby first caught Berg’s eye after seeing a poster that was dropped off at her work promoting a bout.

“I was looking at it, thinking ‘I have no idea what roller derby is, but this artwork is interesting, I’d like to know what it’s about’. A co-worker went to the game, I tagged along, I saw all these strong, fit, powerful women skating really fast and hitting each other and I thought ‘Oh my god, I have to do this, I don’t care what it takes, I have to do this.'", Berg explained. "This is the end of my seventh season.”

The championships will be held at the Royal City Curling Club (75 East 6th Avenue, New Westminster) on July 4 starting at 5 p.m.

Tickets are available in advance at Brownpapertickets.com or at the door for $10 ($5 for kids under 12).
