But there are some challenges in traveling with pets, as the Battleses have discovered.
"The biggest challenge is that there are no pet-sitters on the road so they are pretty much always with us when we travel," Cate said. "That just means we've had to become better planners."
Because most national parks aren't pet-friendly, the Battleses let Frankie and Maggie enjoy the landscapes on the peripheries of the parks. "We will take the animals for a hike just outside of the borders and then take turns to see things inside the park," Cate said. "Definitely not always convenient, but they make the adventure more interesting and they both love to hike."
