Need a little pick-me-up after this week? This should help. Gary Skaggs of San Francisco says the best thing about his job riding a piano bike around town is the smiles it brings to people’s faces.

So check it out below, our thoughts are with all affected by this week’s events, and I hope this brings a smile to your face.The City Exposed: Piano Bike from San Francisco Chronicle on Vimeo.Via Grist.
