Is there any movement under way to actually walk the Chisholm Trail, much as people walk the Pacific Coast Trail, etc.?
Not to my knowledge. The Great Cattle Drive of 1995 took cattle up back roads in a route that roughly paralleled the Chisholm Trail, ultimately ending up somewhere north of western Kansas. People have ridden horseback, also along back roads, and a wagon train (on automobile tires) periodically passes through Duncan along US81. Bicyclists also have followed the trail, using established roads.
