If this weekend had a color scheme, it’d be pink and green. Actually, make that pink and greenway. The Orpheum Theatre screens “Pretty in Pink” in honor of its 30th anniversary (do you feel old yet?), while the Lafitte Greenway encourages participants to explore New Orleans’ wild side. The Julia Street art walk rings in the new month, CeeLo takes Tipitina’s, dachshunds race at the Fairgrounds, and Lark in the Park benefits our other favorite urban green space, City Park.
