Their stage names are Hellacious Kate and Dino Mac, but you might know them as Katie Lockmer and MacKenzie Christinsen.

They are members of the Copper City Queens roller derby team in Butte, and you can catch them in action Saturday at the Butte Civic Center. The Queens will take on the Big Hole Brawlers from Idaho at 6 p.m. That will be the team’s last home bout until October.

Kate is a jammer, meaning she is one of the team members who scores the points. Mac is a blocker. Both are tough as nails, as are all the Copper City players.

Both are also relatively new to the team that began in Butte in 2014, and they both look to be competing in roller derby for years to come.

Tonight I met with Kate and Mac at the Knights of Columbus to talk about roller derby. It was a bit of an educational experience for me. It was also a lot of fun.

Listen in to hear how they got their roller derby names. Listen in to hear that Kate actually has two names. She sometimes skates under the moniker “80’s Katie,” and that name makes her take on a much different persona.

Listen in to hear how they got started in roller derby and why they have no plans to stop. Listen in to hear why you should be heading to the Civic Center on Saturday night.

You can buy tickets on line or from any of the Copper City Queens player in advance of the bout.
