The Seattle Thunderbirds of the Western Hockey League retweeted it. Oak View Group, the company redeveloping the former KeyArena, quoted the tweet and added its own thank you from its Seattle account. So did the Western Washington Female Hockey Association and others.
Barr quoted the tweet too. He said it made him cry. He thanked his 11,000 followers for being part of the journey and told them they had fueled his conviction.
"I get teary-eyed all the time, because I've never wanted to get ahead of it," Barr said. "There's been a couple dark days here in this journey, and it's like, 'What if this never happens? Then what?'"
Well, it has happened now, with his help.
This is someone who discovered hockey because of an NHL expansion team, grew a passion for it and wants others to have a similar experience.
Barr, 45, was born in Philadelphia but grew up in Oakland, California, loving baseball. When the San Jose Sharks joined the NHL in 1991, he wasn't hooked right away. He had just left to go to the University of Nevada, Reno.
Then the Sharks made the Stanley Cup Playoffs in 1993-94.
"I was like, 'Oh, my god. This sport is amazing'," he said.
