Howdy,
Sorry, no collision 
. I just got my 70-200 M2 and I thought I'd take it out for a peak at the Pacific Ocean around the Manhattan Beach Pier (near Los Angeles, CA). You know the story: "Photo hack gets new piece of gear and thinks he can now take better shots" 
. I had fun with both photo and video of surfers, dolphins, and later - sunsets. Super-nice weather this weekend!
Funny; I looked-up and these guys were 5 seconds from this position and I was still sorting-out which end of the lens to point at them 
. (Shot at 200mm).
