Yes the Big E is the Eastern States Exposition Grounds. As for the time of the shows they will most likely begin around 9 AM and go till late afternoon. If there are certain breeds you are particularly interested in seeing you can contact me shortly before leaving for Boston and I will check the judging schedule. This will not be available till about 7-10 days prior to the show.oooh thanks! Is the Big E 'eastern states exposition grounds?' Just want to clarify so I don't go to the wrong place. What time does it start and finish? Vendors? Great! I will make sure to have some cash ready to go shopping!
