Thanks Guys - But it sucks - I really had some time to walk around but that guy was like a bull. 

Best thing of all - I was parking next to him and got out of the car stretching myself, not paying attention at all. Anyway - he felt it and he was suspicious. So he went for a pee to the next tree and that was my moment to take pictures. As he seen that he yelled on me and run over, his pants still be opened .

I wished I would have a better camera and especially I wished that I could have shot that rear lights - that was so clear to see!
