Sos, this is the final version. I'm not sure if people use to add a story to it... I don't have a story, but there is a path that people must follow into this. They first go to the tickets office. They go up to the mountain and there are different building before the gate: toilets, resturant, information... maybe some people stays here will their friends or family go into de park. And the exit building, which is also a gift shop. And then, over the canyon, the gate to check tickets and a big gate to welcome guests into de canyon park!

(If you run this for some minutes some guests stay stuck over the bridge... I like to think that the don't want to go back, the want to get into the park... but there is no park for the moment, sadly)
