I think perhaps it may be a good idea if anyone is not sure what to bring, to let us know here what you actually have available to bring.
At least that way, people can chip in with any comments of interest.
Just a thought.

(With this in mind, I'm probably going to start looking in the 'treasure stashes' in the house soon, to see what gear I still have, then maybe make a list here, so if anyone is interested, I can definitely bring that item to the event).
