My personal opinion is that landscaping does help but there's many other factors in the appeal of a rollercoaster. Terrain, landscape, tunnels/hardscape, and water features all make a ride more unique and aesthetically pleasing. For example I much prefer the trees, tunnels, and scenery around Adventure Express rather than the concrete and gravel around Backlot Stunt Coaster
I'm excited to see the ride identification sign for river racers. I think they have the chance to do something really cool based off The Racers ride logo or do something completely unique.
