As with many units of the National Park System, there are many needs along the Blue Ridge Parkway, a 469-mile-long ribbon of bucolic landscape linking Shenandoah and Great Smoky Mountains national parks. And without the Blue Ridge Parkway Foundation, many of those needs would go wanting and fall into neglect or worse.

eBikes are among the topics making the rounds in the National Park System, as the debate over where these motorized bikes should be allowed to travel is not without controversy. Those cycles, and topics ranging from the lack of a permanent director of the National Park Service to reorganization of the Interior Department, are among the topics Traveler discusses this week with Kristen Brengel, vice president of government affairs for the National Parks Conservation Association, and Phil Francis, chair of the Coalition to Protect America's National Parks. We also take a look at mealtime in the parks, with a focus on Dutch oven cooking.

In this week's episode, we talk with Gemina Garland-Lewis, a photographer, EcoHealth researcher, and National Geographic Explorer about her work in the parks, and how that has changed the way she experiences parks themselves.

Next, we pay a visit to the Schoodic Peninsula in Acadia National Park, a quieter part of the National Park System. Finally, we end with a look at Walnut Canyon and Montezuma Castle national monuments, which are easy day trips from Flagstaff, Arizona, that open windows into past cultures.

Tom Smith, a professor of wildlife sciences at Brigham Young University and a member of the National Rifle Association, discusses how effective guns in backcountry locations are in defending against bear attacks. What he says might surprise you. This episode also looks at the Volcanic Legacy Highway that ties Lassen Volcanic National Park and Crater Lake National Park together.
