Tuesday’s second annual Soul Food Dinner at Penn College, which attracted a diverse (and ultimately well-fed) audience to the Bush Campus Center, blended a mouth-watering menu of ethnic favorites with a showing of Byron Hurt’s “Soul Food Junkies” documentary. The filmmaker is touring the country introducing his movie, which has been  broadcast on PBS to wide acclaim, and drew a sold-out crowd on the Williamsport leg of his map-hopping itinerary.
