Ken’s wife Christine and children Zach and Shelby keep Ken going through out the year.  Ken works for Zebra Technologies in Greenville, WI as a Maintenance Lead /MRO Procurement Specialist. Christine also helps with the hospitality, photography and keeping the website up to date.

Dan’s wife Laura and two children Kathryn and Caleb support him in grand style whether off racing or at home.  Dan is the Service Manager for Lenz Truck Center in Fond du Lac, WI.

Craig’s wife Jody and daughter Kat keep him running strong all year. Craig is a Honda automotive technician for Bergstrom Honda in Oshkosh, WI

Jeff is the new guy on the team this year. He is a Pyrotechnican Specialist based out of the Fox Valley.

Jim, Jon, Craig and Dan have all been involved in organized four wheel drive organizations for 10-15 years.  We still wheel recreationally when the opportunity presents itself.  If it weren’t for our families we would never be able to race and live like we do.
