I've actually seen signs for this festival from the highway on my last trip from Chicago to NYS (we go through Canada). Too bad it's on a weekend that we're on vacation and no able to go. My DH loves the wineries in Michigan so it would have been a win-win for us!
I've considered moving there when my knitting group and I took a road trip to Threadbear Fiber Arts in Lansing MI (formerly in Indiana) It was absolutely the most incredible yarn shop I have ever seen in my life and I immediately wanted to move in right next door.
I am already thinking of planning another trip there because it was just so darn wonderful and I miss it!
