Many thanks to byingtonwinery for sharing a photo of Keanu on instagram. The photo was taken at the end of August when Keanu was there.
The winery also posted the photo on their FB page along with the following comment.
SURPRISE guest last weekend to Byington! Everyone’s favorite actor, KEANU REEVES!!! We thank him for his visit and his gracious time taking photos with other guests, and a staff member, pictured here! Looking forward to seeing his new movie, Destination Wedding!!!
From one of the comments, it becomes clear that Michelle Lee Ballestrasse is the lady in the photo. Many thanks to her as she shared the photo on her FB page as well along with a photo of the bikes out in the parking lot which are here.
