Fraternities and sororities from the University of Utah's Greek system volunteer to take children from Neighborhood House on a field trip to Hogle Zoo Wednesday, April 3, 2013, in Salt Lake City.

SALT LAKE CITY — The University of Utah's fraternity and sorority members enjoyed a day at the zoo with young folks on Tuesday.

Every year, the U. Greek system has a series of events called "Greek Week" in which fraternities and sororities team up in specific competitions. At the end of the week there is an overall winner.

One of the annual competitions is a service day at Hogle Zoo in which students take kids from Neighborhood House and show them around the zoo.
