The parks we've come across in Europe could never be built in America because they'd give too many people too many reasons to sue whoever designed them, built them and maintained them. In other words, the parks we've seen here are a lot more fun than the ones in America.
So here's the first in what I plan to be a series of Parks Lawyers Would Never Build.
U.S. LAWYER SOLUTION: Secure the walking area with netting on both sides of the planks. Also, use more planks to transform the zig-zag platform into a solid floor. The wood should then be be thoroughly sanded.
