Fun-snacks-and-ice-cold-drinks-aplenty bash to beat the heat: Live Baltimore hosts an “I Love City Life” happy hour this evening to say thanks to folks who’ve sported the local city-life-loving slogan on bumpers or license plates.

Jot down the details: 6 to 8pm at Gaslight Square, 1401 Severn Street.

Maybe you recognize the widespread yellow sticker but don’t know that the message links to Live Baltimore, the only organization dedicated to marketing Baltimore as a terrific and affordable place to live, with the two practical goals of repopulating the city and increasing its residential tax base. (If you didn’t know the sticker matched the nonprofit, you’re not alone!)

Baltimore City native Carolyn O’Keefe dreamed up the saying to express her true satisfaction with life in the city. She created a bumper sticker and awarded it to friendly people she met–at gas stations, groceries, wherever. New face by new face and neighbor by neighbor, O’Keefe spread her pro-city message. Since 1999, when O’Keefe donated stickers to Live Baltimore, the nonprofit has proudly touted “I Love City Life” as catchphrase, theme song, and battle hymn.

Tonight’s happy hour will help raise awareness for the Baltimore Grand Prix, which takes place Labor Day weekend, September 2-4, and marks the first time the “Festival of Speed” has zoomed through town.

“We created this event to celebrate a marriage – of city lovers and car lovers,” said Live Baltimore Executive Director Anna Custer-Singh. “This happy hour is intended to thank all of our license plate holders and raise awareness of a new Baltimore tradition, the Baltimore Grand Prix.”

A 10 dollar cover charge includes appetizers and drinks from Dogwood, Taharka Brothers Ice Cream, live music, and a shot at two Grand Prix tickets.

(Those who own an “I Love” license plate get free admittance!)

Online pre-registration is encouraged.
