What a great weekend at the Jefferson County Rodeo.

We enjoyed connecting with so many members of our community, meeting new faces, and supporting an event that brings our community together. Thank you to everyone who stopped by our booth, shared a conversation, and helped make the weekend a success.

STL Diesel is proud to serve this community on and off the road. Thank you for the opportunity to be a part of such a great American tradition. We’ll see you next month at the County Fair!
