Sunday night they pick a destination for the following Wednesday. Several different chapters of the organization in Kansas. Don't know if it's nation wide or not. Last ride I went on had 46 people show up at the small cafe. They give the cafe/bar a heads up of approx how many people could show up. No commitment on anyone's part you simply ride to the destination.
Gives me a chance to ride that I would probably not do by myself, (always projects). Kind of neat seeing these small towns that I would probably not go to as well. The small group I ride with from McPherson we always take 2 lane senic highways and avoid the interstate. You can ride on your own as well.
