It's still summer. It won't turn fall until later this month. But for many of us, Labor Day signals the unofficial end of summer.
It's back to school, back to work after family vacations -- and in Montana, we start feeling the weather change.
To get a taste of Labor Day family style, NBC Montana visited a very large and active Missoula family, the Hasselbrooks.
Nine Hasselbrook boys channel energy onto bikes, and trees and swings on Labor Day.
Summer's unofficially over. School begins.
"Some of our guys in high school started already," said Dave Hasselbrook, the patriarch of the family. "But the rest of the kids that aren't in high school are home schooled, and so it's kind of like the last hurrah."
There's nonstop heavy traffic in the family yard. Bicycles are flying everywhere. Kids are swinging in swings and climbing trees.
"I want to do as much as I can today before we start school," said one of the boys.
His brother said he's looking forward to school.
The oldest son, who's a high school senior, said "being with family" is important. He said he enjoys this day and the cookout the family is having because he gets to spend precious time with his siblings.
Their dad, Dave Hasselbrook, is Pastor of Messiah Lutheran Church in Missoula.
