By laying down plentiful wooden planks, all-weather roads were built in the mid-1800s, accommodating floods of immigrants headed west. The Old Plank Road Trail parallels Hwy. 23 - the original plank road route. This popular, 17 mile, American Planning Association award-winning trail accommodates bicyclists, runners, walkers, in-line skaters, horseback riders, moped users, nordic skiers, and snowmobilers on 10 feet of asphalt and 8 feet of turf. It's seldom flat, making for more interest and exertion than many other trails. It stretches from the City of Sheboygan to the village of Greenbush, where you can tour the Wade House, a restored stagecoach inn from the plank road days. Along the way, the trail skirts Plymouth which has a lovely downtown historic district. What more do you need to make you head west?
