Someone chalked a message on a Wrigley Field brick wall last year, starting a gigantic love letter to the Cubs.
It quickly grew in size and in layers of bright colors as fans wrote encouragement and pleas for a World Series victory to end a 108-year dry spell.
Now, the Wrigley chalk wall is back, enshrined for some as part of the winning karma they hope will carry the Cubs to a division series victory in Game 5 Thursday in Washington D.C.
Wearing a green vest, green hat and carrying a box of Lucky Charms, "Driver Tom" McCarthy, a well-known limo driver from Elgin, stopped by Wrigley this week to write the names of people he knows on the ballpark's brick outer walls, being careful to keep to his 2016 routine.
"I walked around Wrigley Field last year and they won!" he said. "I'm just wishin' the Cubs good luck. If it didn't work I wouldn't be doing it."
Larry Scott of Glen Ellyn chalked a memory to his grandmother. "She just passed away in September ... biggest Cubs fan ever. I was thrilled she got to see them win the World Series last year. But hopefully they win two for two," Scott said.
"Win Two For Sue RIP 12-21-30. 09-13-17," he wrote.
Though they wash away, the chalk messages aren't so ephemeral. McCarthy photographed his and posted it to Facebook.
And last year's chalk wall? Part of it reappeared this spring as a life-size photo decorating a hallway outside the home clubhouse at Wrigley.
