Flying a drone/quad copter in the New Orleans City Park is a no...no. No R/C craft allowed anywhere in the Park especially near their new golf course. If you fly a drone there, you will certinally get a visit from the Park Police and NOPD.
Another place you recomended was Laketown Pier in Kenner, not allowed. Laketown at the end of Williams Blvd at the lake is under a landing pattern for commercial aircraft going to MSY Airport. Heads up, flying there you will get a visit from Kenner PD and Airport Police, with possible visit to HQ. Just not worth it!!
