by Mike Krumboltz An economy on the brink. Horrible pollution. And now a "carpet of frogs" to contend with? Greece sure has it tough these days. On Wednesday, a horde of frogs caused a two-hour closure on one of Greece's major highways near the city of Thessaloniki. The city's traffic police chief Giorgos Thanoglou says that the "millions" of frogs were likely looking for food. Three accidents resulted, as drivers attempted to dodge the hungry hoppers.
