Much of their travel is done on weekends, mainly because of Brady's collegiate schedule.
"Normally Keith and I go separately and try to divide and conquer," Chantal said.
For example …
"I try to see Brady monthly whether it's at BU or somewhere on the road," Chantal said. "We had a great time in Buffalo for the World Juniors with Brady and had grandparents and aunts and uncles with us.
"We saw Matthew in St. Louis in October (with the Flames), and then I went for a long homestand in Calgary in November and Keith went in December. We met Matthew in Arizona over the (NHL) All-Star break in January and he came to watch Brady when BU played [Arizona State].
"It was the first time all five of us were in one place since August, so I was in heaven."
That's not all of it.
Taryn is on a traveling club team, meaning more trips for her parents. She also is starting to make college visits, mostly accompanied by her father, who is happy to be out of the freezing arenas, if ever so briefly.
"She tried it (ice hockey) one year but she quit and it was music to my ears," Keith said. "Then she played competitive soccer. When I used to travel with (the boys), we'd be in some cold cities. Now we're in Florida quite a bit, Texas … it doesn't get any better than that."
Chantal said Taryn has watched so much NHL hockey and is so informative that she probably could become a scout.
"She's competitive like her brothers and she does well athletically," Chantal said. "A lot of it is because of her brothers, trying to keep up with them when she was younger. But she's our family ham."
Hockey is in the family DNA, and the highly accomplished Tkachuks don't mind being front and center.
Chantal is from Winnipeg and her father, Don Oster, is so wrapped up in the performance of his grandchildren, he gave up his beloved Winnipeg Jets season tickets, which he had since 2011, because there were too many conflicts. He wanted to be home to be able to watch Calgary Flames and Boston University games.
Calgary (32-25-9, 73 points) trails the Anaheim Ducks by three points for the second wild card into the playoffs from the Western Conference.
Keith, born in Melrose, Massachusetts, also starred at BU before making his mark as the League's quintessential power forward. Playing for the Winnipeg Jets (who drafted him No. 19 in the 1990 NHL Draft), Phoenix Coyotes, St. Louis Blues and Atlanta Thrashers, he ranks third in goals (538) and fifth in points (1,065) among U.S.-born players. He played parts of nine seasons (2000-10) with the Blues before retiring.
Matthew was born in Arizona, shortly after the Jets had relocated to Phoenix and several months after his dad led the League with 52 goals in 1996-97. Those early days at the Coyotes practice rink in Scottsdale were almost like a day care center for him.
