Many thanks to Lou Giovanni who shared a photo of Keanu Reeves out on the street filming a scene on his FB page and to @_Nina_0715 for tweeting the link.
The photo was posted today. If you look across the street in the background, you can see snow on the ground that is near the parking meters lining the street. If you look at the other photos of Keanu from today, the side walks were clear of snow in those as well with the snow collected near the meters/street.I think this photo is from today.
