IMO bring only what you are willing to a)trade or
sell, and b)what you don't mind getting damaged.
This means of course you need to search though
your collection and decide what to bring first. If
you are considering bringing your whole
collection, just to share, use the net and a free
gallery link RS. It would be foolish to bring your
collection even if it is not high end cels and
possibly get them damaged or worse, stolen.
