The annual Arthritis Foundation Bone Bash is a chic Halloween soiree to support the organization’s fight against arthritis, the nation’s most common cause of disability. Guests adorned in costumes and masks will mix and mingle with zombies, ghouls, witches and ghosts as they roam - or float - throughout the Perot Museum of Nature and Science, dine on New Orleans-style cuisine from Wolfgang Puck and rattle their bones to the jive rhythms of The Crescent City’s own psychedelic jazz/rock and funk band “Flowtribe.”
