And Finland is very expensive for us Central Europeans
On the WC2017 FAQ it seems to only bottles are not allowed in the arena, but food is permitted. I think I'll give it a try on the first day, I will bring biscuits/chocolate and see if the security stuff lets them it.
St Louis Nationals some years ago security chased my 80-year-old mother down the concourse because she dared to sneak in a sticky bun from breakfast. Boston Worlds last year I managed to discreetly bring some food in, as I have at most Nationals. At Helsinki I'm going bring some plastic baggies to bring in my leftover breakfast and an empty plastic bottle to refill. We'll see. Between the flight and the hotel cost, it's already very, very expensive to be there.
