You don't normally see ice hockey in the summer, but that's what thousands of people came out to see Thursday in Stamford.

A boatload of screaming fans lined up outside Terry Conners Rink to get autographs and pictures with their favorite NHL players.

“I’m shaking," said Chris Kreider superfan Laura Talbot. "I’m really super excited because it’s amazing."

The "Shoulder Check" showcase has quickly become a cherished tradition around these parts.

The HT40 foundation started the mental health movement following the sudden and unexpected death of Darien hockey player Hayden Thorson.

Hayden’s father, Rob Thorsen, says it’s all about reaching out and checking in with one another.

“It’s a give-back sport, it’s a rally-around-people sport," says Thorsen. "This is a chance for everybody to see what it’s all about and see how they can get involved."

Most of the 30 hockey stars in attendance pledged to come back next year because the cause is so important.

"From where it started with all the New York Rangers guys a couple years ago, and now to see guys come from a lot of teams," said former New York Ranger Frank Vatrano. "To do it for a cause like this, it’s great and I think it’s only going to get bigger."
