The FFM is a huge event that draws many, many people from not just Connecticut but also surrounding states. There you will see venders that come from all across the country. It can be a bit overwhelming due to the shear size of the event but something you need to experience. It does get crowded at the event so bringing small children might be a challenge, but not impossible. Pack your patience!
I get there early, shop around, spend lots of $$, hang out a bit then I'm out of there! That's my game plan but you can do it however best suits your needs.
After the FFM post your experience here and tell us what you think. I know you're going to be blown away!
