As befits a big project, there were a lot of shovels at work when ground was ceremonially broken Monday for the future County Materials Complex on Monday along Menomonie Street in Eau Claire.  Front and center were Carolyn and John Sonnentag, whose record-setting $70 million gift to UW-Eau Claire, their alma mater, made the project possible. They were flanked by UWEC Chancellor James Schmidt and Dr. Gianrico Farrugia, president and CEO of Mayo Clinic, which is also a partner in the multifaceted project.
