GRASS VALLEY, Calif. — This makeshift sign spoke volumes to my wife and me as we arrived in this small town in the foothills of the Sierra Nevada.

They’re fighting a fire here. It’s not as devastating and tragic as the Santa Rosa fire that is blazing in California’s famed Wine Country near the Pacific Coast. It’s still pretty big.

Residents of Grass Valley and Nevada County have expressed their thanks to the men and women who have come here from far away to battle the fire near Grass Valley.

Children have written the messages. They have offered their own love and blessings and asked for blessings from God. They have urged the firefighters to stay safe to enable a safe return to their own families.

We’ve offered our own expressions of gratitude for what these men and women do. They sign on to protect and to serve. They answer the call. They rush toward the danger, not away from it.

None of this has been lost on the people they are protecting and serving, as my wife and I noticed upon our arrival at an RV park at the Nevada County Fairgrounds, which have become a staging area for roughly 1,000 firefighters who’ve come here to fight Mother Nature’s red-hot wrath.

I’ve seen these men and women do their duty up close back home in the Texas Panhandle, where we’ve lived for more than two decades. Wildfires have ravaged our landscape over the years, too. They have destroyed homes, killed livestock and, yes, taken some human lives too. The firefighters have braved dastardly wind that often sweeps across the High Plains. I salute them every chance I get.

I am doing so again as my wife and I watch these young firefighters prepare to enter the field of battle against the flames.

I am absolutely certain they appreciate the community’s expression of gratitude displayed on that chain-link fence that surrounds their base camp. They are in our thoughts and prayers.
