Magnum Opus 2012. So Tim & I are resurrecting the Magnum Opus, last run over 10 years ago and HQ'd in Munising, MI. This will be a 1-day regional gravel stage rally HQ'd out of Newberry, home of Tahquamenon Falls. We spent last weekend picking out the special stage & transit roads. We're working with Rally America for sanctioning and early interest amongst competitors is strong. We're shooting for April 21 and the road conditions could be snow, ice, mud, wet, slush, dry .... or, more likely, a combination of them all.
