One tree-seller knows the best way to sell to Upper West Siders: appeal to our longing for freedom from gluten.

The photo is from Caitlin Hawke, who explained why she loves the season in a blog post on the website for the 102nd-103rd Street Block Association. The post calls on locals to come out to the association’s caroling event at 7 p.m. on Dec. 21 this year:

“So this December 21st, on the heels of that traffic-stopping eclipse which reminded us of our puny place on the third rock from the sun, come into the streets and sing. Come mittened. Come gloved. Come sing with your neighbors, known and unknown. Sing on your streets! Sing under windows and on stoops. Stand in the doorways and block up the halls. Sing out loud. Sing out strong. Sing off-key. Sing joyous or blue. Sing 2017 out.”
