It is one week before I head back to Austin after a two-month stay in New Zealand. While Texas is experiencing record heat and drought, Christchurch is having its second snow day this winter. Heavy snow falls here only about once every 10 years, so to have two big snow days three weeks apart is quite unusual. The University of Canterbury is closed today, but hopefully will be back to normal before my class on Wednesday. I expect major shock when I get off the plane in seven days.
