I have been twice - and both times I felt I was walking around and around and around a rather tight area and seeing the same things over and again .. LOTS AND LOTS OF VENDORS .. mostly for crafty things. A few booths offered make-it and take-it things. BE AWARE that parking is a bit of a nightmare.. follow the signs and you will get to the r ight place.
It isn't the easiest of locations. Last year my friend used her new GPS .. it took us well over an hour to make a 15 minute trip from my house.
Just like eating clams - it's good to try it once!
