Which communities/parks have started a spring out door concert series that is kid friendly? 

Kid friendly concerts are booked this year at Centennial Park, Callanwolde Fine Art Center, Stone Mountain and Six Flags

My son's band, Second Wave, is playing tomorrow outdoors, on the steps of the GA state capital building. 11:15am. It's a rally for the Nat'l Day of Prayer. Come one, come all!

Decatur has a "Concerts on the Square" series every Saturday night from 7 - 9:30PM during the months of May and September.  Folks are welcome to bring a blanket or quilt with their picnic and set up on the grass around the Old Courthouse near the community bandstand. 

Decatur is very family-friendly and friends of mine have raved about the concerts.  I'm hoping to go tomorrow night when the new series starts - this Saturday, May 3rd, at 7PM.  Be sure to arrive early to find your spot!

The Concerts on the Square are great.

I used to live on the southern side of Decatur in the Oakhurst neighborhood.  While the Concerts on the Square were just a short walk on Saturdays, the Jazz Concerts at the Old Scottish Rite building in Oakhurst were pretty cool too and that much closer.  I think they still do them Thursday nights in April and September.
