A 20-foot billboard was not enough to help a Brooklyn woman find her missed connection on Valentine's Day.

Devin Custalow, 25, stood near the billboard on the corner of Wythe Avenue and North 10th Street, waiting to see if the mystery man she briefly met on the G train in October would arrive. She says the two made eye contact and smiled at each other, but she got nervous and never got a chance to talk to him. 

Custalow told News 12 she posted messages on the “Missed Connections” section of Craigslist and it piqued the interest of a Las Vegas hotel. The hotel created a billboard, asking the mystery man to meet Custalow on Valentine's Day at 1 p.m.

"Everyone else is the same boat whether or not they say they are…everyone experienced it," she says. 

After waiting 30 minutes, the man who was wearing the yellow shoes on the G train that day never showed up. Despite the outcome, Custalow says the experience changed her life and she hopes she has encouraged others.
