If eating pizza is any indication of a person's character, Provo is in good hands with Mayor Joe Jenkins. With no inhibitions, the mayor helped down two pizzas Thursday in celebration of National Pizza Week. Jenkins and his staff feasted on the pizza at a noon-time party sponsored by Utah Pizza Service Inc., one of the Little Caesars Pizza franchise holders in the state. Pizza parties were also held at top administrative offices in Orem, Ogden, Logan and Salt Lake City this week. The State Senate and House of Representatives also joined the week's activities at a pizza celebration. National Pizza Week began in 1986.
