Its a different approach to running a business. "Minnetonka natives Chad Mayes, Jason Landstrom and Ryan Johnson love beer. They also love our lakes. They put the two together to establish the Tonka Beer Co., a craft brewery that donates 100 percent of its profits to Save-Our-Lakes to battle the onslaught of lake-choking invasive species like zebra mussels." That was an excerpt from a company profile in the latest issue of Lake Minnetonka Magazine. In their first year as a start up company, Tonka Beer and its associated Save-The-Lakes Foundation have already raised $10,000 for their cause. The first grant was given out last month to fund invasive species research at the University of Minnesota. Its a win-win for all of us who care about Minnesota's lakes.
