Sorry for the short notice on this.
I have a small group discussing an Oct 10-12 day hiking weekend. The idea is to basecamp in the driveup sites in Jay Cooke State Park and day hike sections of the SHT in Duluth, or maybe the new sections recently completed near Two Harbors depending on where the fall colors seem best.
It'd be up to individual's to make arrangements for camping at the park (or conspire with others to share a site). I just checked and there are plenty of sites not reserved. Since this is not a backpacking trip, there'd be flexibility for folks who can't make it all three days.
