It sounds like rain for the weekend. You're gonna get wet anyway, so why not have fun paddling in it?
I will be paddling Upper St. Marys Saturday morning with my bro and a beginner. It will be a great opportunity for those who are just learning some river-running skills to get some extra direction and practice on a fun class II river. If you are interested, leave a comment, and I'll get some more specifics for you.
