Though most of the main highway has a shoulder, it is nicer to bike away from it on the sections of dedicated bike trail or, where it is missing, on the Old Jackson Highway. At this intersection of Trail Creek and a smaller creek named after Mike Harris is a large forest shaded campground on the west side of the highway and creek.
