My experiences with events at City Park have always been good (Martini Madness is a fantastic party). The lineup for the upcoming "Hogs for the Cause" event looks awesome, as does the ticket price.
For $10 advance/$15 you get to try a whole bunch of BBQ and vote for the cook off winner while listening to the music stylings of:
-Honey Island Swamp Band
-Soul Rebels Brass Band
-Anders Osborne with Big Chief Monk Boudreaux
All the money goes to the families of children with brain cancer.
