Extreme Team: Making spirits Bright for children, staff at Sacred Heart Children's Hospital

SPOKANE, Wash. — 4 News Now and the Extreme Teams are celebrating the 10th year of filling Spokane’s Cowley Park with holiday lights.

It’s 4 News Now’s way of spreading holiday cheer—not only to visitors of the park but also to families at Sacred Heart Children’s Hospital across the street.

Each year, Mark Peterson leads the effort to decorate the trees with thousands of lights.

You can watch 4 News Now at 6 p.m. daily to see all the work that goes into the display ahead of the big reveal Thursday, Dec. 4.
