Hi kabelhaai, 
I'm don't interact anymore with people who lie, it's a waste of time. If you want, we can go on the location together and I will show you that the way still exists. The track on the photo is not overgrown, grass grows and dies depending on several conditions. Anyway for a for a 4 wheeled vehicle the way is usuable. I've been there in March, it still exists. Here is an activity showing I've been on location
