I don't think they open till March
Shelley nailed it
It is open year round with the exception of when there is snow that needs plowed. Like their Facebook page to get updates of any closures. FYI...they were open today. "In season" is considered April-October. That's when you'll see the most vendors.
April
Depends on weather. Hope the end of april
Open all year, weather permitting... But really it starts to fill up around March/April.
