They could plant some along the train tracks whether there is room between the train and the pipeline. Also perhaps some on the Griffon and Loch Ness side of the train. But there are already some trees there just none of them have any leaves at the moment.
I think it's more likely to see some planted around FF.
It's important to keep in mind that the trees have not filled in yet for the spring. I think the entire area surrounding the ride will look much better in summer.
Im guessing it is a way of them not having to install a railing that would need to be lowered away at the start of every ride. Basically it is stairs that goes down to the point that the handrail is below the level of the decking but still has the height needed to pass code. If you look on rides like Griffon that have the same thing just before the big drop and at the end of the walking platform.
I was looking at some of the photos and noticed that each swing has a set of seats with red on them near the restraints. Does anyone know if it has larger rider seats? If it doesn't any idea what the difference is?
