Great Morning

Thanks to Big Ridge Elementary School/Big Ridge Elementary PTA for letting us be a part of Career Day. It was exciting talking to students about how you can turn your passion into a business. And spoiler alert: kids are obsessed with camper bunk beds.

Big shoutout to Southeast Diesel Inc for partnering with us on this fun event! It’s always great seeing family owned businesses supporting each other.

We hope to see many Big Ridge Families around the campfire this summer 🔥
