Back before it was possible to cram video recording stuff into something the size of some matchboxes or in a phone you needed to be a bit more enterprising for how you captured your video on the move. So for skiing I had a contraption which was a bullet camera, mic and remote all feeding to my rucksack which contained camcorder and a tuppaware tub full of batteries/cables... Somehow I was never questioned over dragging all that lot through customs etc.
On a long weekend to Budapest I had crammed my rucksack with a camera, phone, iPod and all the OTT charging/connectivity cables etc. When the rucksack went though the x-ray scanner the operator looked at the screen, looked and me, and then turned to his mate and said "James Bond". I'm sure Bond would have less obvious sky kit...
