We’re gearing up for the Wounded Warrior Project® Carry Forward 5K in North Carolina on October 25th! 🎽💛 One of our Cornerstone Defense team members will be lacing up and joining the mission to honor and empower wounded warriors, and we couldn’t be more proud!
We’ll be bringing along some Cornerstone swag (coolers + koozies and more!) to hand out at the event as we show our support.
The Carry Forward 5K isn’t just a run—it’s a powerful way to stand behind the brave men and women who’ve served our country. At Cornerstone Defense, many of the programs and missions we support in our industry are made possible by the sacrifices of our service members, so this cause is close to our hearts.
If you feel called to support Team Yellow Ribbon (our staff member’s team), you can do so at the link ! 👉 carryforward.woundedwarriorproject.org/teams/teamyellowribbon
We’re kicking off a new series: “Name the Local Spot!” 🎉 We’ve been proud to call Herndon home for over 10 years, and we truly consider ourselves part of this community. 💙 So, we certainly love when someone tells us they spotted a Cornerstone Defense glass out in the wild at one of our favorite local hangouts. So let’s play a game—can you figure out where this is? 👀
Here’s your hint (in rhyme, of course):
A place where stories, music, and cheer,
Fill up the night with friends far and near.
The name may recall a legend’s fame,
But can you guess this spot by name?
Drop your best guesses below ⬇️ and tell us… what are your favorite Herndon area spots?! There are so many good ones!
