Would you take a flask to a dry wedding?

I have never heard of anyone having a dry wedding. I think if invites went out and it was known that no alcohol would be served everyone would assume it was BYO and bring eskies. But I'm Australian and apparently we drink more than any other country lol.

I don't know if I would bring a flask (haha but as I said above an esky would not be out of the question). Flasks are very small. But I would be at a bar before the wedding, in between if there is time, and I would probably leave early when it got boring and go to a bar and I assume I would be with most of the guests at the bar.
