Yes, Equine Affaire is in West Springfield, MA, not far from I-91 and near the CT state line. They hold it at "The Big E" -- otherwise known as the Eastern States Exposition Center.
Just FYI, there's a lot to see. It's spread out among several buildings on the grounds. My advice is to check the Equine Affaire website to get the schedule of clinicians and their locations on the complex.
They have food in several places, including an outdoor courtyard where there are "fair booths." They'll have a tent to sit it. Plus, one building has a sit-down restaurant that's always packed.
At least two of the exhibit halls are full of equestrian needs (and wants) booths. It's like a big horse-stuff mall. You can even browse trailers and pickups, if you're shopping.
I'll miss seeing you guys.
I live about an hour away, but I'll be in Florida that week. (I know -- woe is me.
