last year it was all inside, its small for a champ show as its only in its 2nd year, I think it was in two halls with tents joining the halls with the trade stands in.
Aparently it is VERY cold!!!!! And in the equivalent to warehouses!!!! Now I havnt been to many shows so dont know what they are normally like, but thats from someone who has a trade stand at Newark every week LOL Lea :)
We have our breed club show at newark and it is always lovely and warm (they have heaters on the ceiling ;) ) I cant remember if they put these on for the Boston show though.
