I put this out on another forum and got some interest. There may be a few here as well, especially from the Chicago area.
Along my travels the past years a few people have asked about a bike rally in Michigan. Of course there are a lot of places many people would like along the lakeshore, but I realized that two things which have reached international importance are right out my back door and I do it every year. Every year around the end of Sept I ride up to Yankee Springs Campground and spend the weekend where I ride through the forest along the route of the Barry Roubaix gravel race and spend the following day riding (or driving/riding, depending on the weather) to Grand Rapids for the Art Prize competition.
I thought I would throw that out there and invite anybody who wishes to tag along. It would be the last weekend of September 2015.
