From photos that have appeared on instagram, Keanu appears to be in Bologna.
Many thanks to mrme_h for sharing his selfie with Keanu on instagram. The photo was taken this morning.
Many thanks to ___joe.t___ for sharing a photo on instagram and two on IG story. Photos were taken this morning at the hotel after breakfast.
Update: Many thanks to Ristorante Da Nello al Montegrappa for sharing a photo of Keanu with the chef and perhaps owner on FB.
As an aside Ryan Boyd posted a photo from Suter Racing in Turbenthal, Switzerland on instagram along with a comment that he would be there for a minute. It is not clear if there is anyone else from Arch there with him.
