When the 1993 movie Groundhog Day was filmed in Woodstock, Starbucks was not yet on the square. So I guess we can narrow the date of its appearance to sometime between 1993 and 2000.
It was there when I moved to Woodstock as a kid. So at least since 2000.
There's almost no way to find that out unless you speak to either the corporate office or find a customer that was here for it's opening
