Aw, going to miss it by a week! Glad we at least went on the island last year.
On the new art: I like that they will keep some water along the Frontierland walkway!
Edit to add: Looks like trees and such will provide barriers and sightline covers between old Frontierland and Piston Peak National Park:
"Welcome to Piston Peak National Park
Imagine an awe-inspiring wilderness filled with towering trees, snowcapped mountains, breathtaking waterfalls, roaring rivers and impressive geysers. While fictional, Piston Peak is inspired by the Rocky Mountain area and the history and iconic sights of the American Frontier and its national parks.
Inside Piston Peak, guests will be able to see and explore the visitor lodge, Ranger HQ, trails and more all set within the Disney and Pixar “Cars” universe. To make sure these buildings fit naturally within the surrounding majestic landscapes, Imagineers are using a style of architecture called “Parkitecture,” which was developed by the National Park Service to create structures that harmonize with the natural environment.
From the outside, trees will provide a natural barrier between the off-road rally and other parts of Frontierland and Liberty Square. Rugged mountains with dramatic peaks will be nestled along a calming waterway across from Grizzly Hall and soaring geysers from the famed Big Thunder Mountain Railroad will stretch into the trails of our off-road rally."
