Don't believe the hype: Mountain biking really can thrive on the pancake topography of the American Heartland. We talk to Chris Van Roekel with the nonprofit Whiterock Conservancy near Coon Rapids, Iowa. He tends 38 miles of mountain bike trails nestled into central Iowa, on historic farmland that played a crucial role in U.S.-Soviet relations at the height of the Cold War. ... Andrea Parrott on this week's "Parrott Talk" welcomes a guest to chat about the national trend of women's bike rides, including the Pigtails Ride (pigtailsride.com) May 20 in central Iowa. ... We also hear from our dear listeners and fellow bicyclists who joined us for our inaugural Just Go Bike Meetup Ride!
