Consider taking your small group on a spiritual retreat
During high school, my youth group would go every fall to a camp that sat high on a dune above Lake Michigan. By October the air was crisp and full of the scent of burning leaves, the lake choppy and layered in shades of blue and gray—all heralding the change of seasons. The weekend held the promise of all-night girl gab sessions, midnight hikes up the dunes, and intense small-group discussions. I couldn't get my sleeping bag in the van fast enough.
