Which historic person would you like to hike, ski, or paddle with in a national park?
Would you take John Muir to show him what Yosemite National Park looks like now? Maybe you would hike with Benton MacKaye so he can see how his vision of the Appalachian Trail turned out. What would you talk about?
Alternatively, forget these outdoor icons. Instead, you would bring over your great-grandfather from the old country and show him Picture Rocks National Lakeshore.
Or you could mix it all up and take Henry Thoreau to Yellowstone National Park and explain today's philosophy of national parks.
Whom would you choose and where would you take them?
