Cheers everyone for the feedback - difficult conditions for sure but the challenge made it somewhat more fun in a bizzare way, security was tight at the barrier, long before the display a guy ran through that area and got chased by security guards on foot and a van, they caught the guy and brought him back again, they went to a big effort to get him.
Hand isn't too bad at all, just a superifical wound which bleeds in dramatic fashion when there's no serious inury, have the tetnous injunction anyway so all is fine.
- until my next adventure.
Hope to be shooting the Maghera display tonight if all goes well...
