Hello from the Arizona Winter School, which is an annual program for graduate students in number theory that takes place neither in Arizona nor in Winter. This year it happens to be in Albuquerque, so I'm posting from the living room of Nat and Almea, who have a very cozy place very near campus and have even offered to lend me their car to explore the area (since public transit appears to be a concept foreign to New Mexicans). More later...Almea's cooked burritos and I'm told they're ready!
