I had a great one last year, my first real one amongst many near misses. I was running backwards along a corridor (535/ Ultra) with loads of extras popping out of doorways and had to go fast backwards up a ramp and then through another door (no DJ as the corridor was really too narrow) I ended up pulling the rig too close to myself as I hit the ramp on one take and INSTANTANEOUSLY I was on my arse holding the rig above me. Damage to rig: NIL, Damage to pride: 1. I guess sometimes its okay to have a bit of pading back there...
I normally use a spotter but in this case there was no way he could even get near me. Most experiences I've had with near misses are so quick I would be very impressed if someone managed to grab on to me or the rig. I have some great help and those guys know that the best they may be able to do sometimes is give me a hard tug or push, puling the rig back in toward me.
Then there was the time I had to go home with a bad mosquito bite and the guy subbing for me agreed to do the run down that big sand dune...whoops
