I used to do the Michigander every year (fat tire tour to benefit Michigan Rails to Trails) and the cyclists I got to know never tired of gushing about Dalmac, especially the Mackinaw bridge crossing (I think both were sponsored in part by the same newspaper.)
Also would go on about the Bow Tie (google says it's the "Shoreline Bow Tie Bicycle Tour" but I can't find a link that's clearly for 2010).
